Wow, I am surprised that withholdings would equal US liability. Since pension income is taxed by the US (source) at ordinary rates which vary, I didn't think a treaty would stipulate the US rate of tax and thus the withholding may be too much or too little depending on which bracket was ended up in.
The extent to which this works depends a lot on the country, and the type of pension. It's not so much that treaties stipulate a rate for pensions; rather that they either reserve tax to either the other country (so withholding is 0%), or to the US (so withholding at some standard IRS-prescribed rate). In some cases then, 0% withholding and 0% US tax liability means it'd be pointless filing a 1040-NR for that.
The only treaty I'm fully familiar with, US/UK, says that for a
non-US person (that is, not a US citizen -- the US overrides a lot of the treaty for them with its 'saving clause'), both private pension withdrawals (401k, IRA, and so on) and US social security are taxable only to the UK. Provided that a) you supply the payers with enough W-8BEN forms to satisfy their own internal processes (for Vanguard, that's one for each account; silly, but that's their rule), and b) the payers set withholding to match the treaty rates, in this case 0%, no US tax filing requirement.
(So, lucky me. I'm in the UK. I receive US SS payments, some interest and dividends from lingering US taxable accounts, and yet don't have to file any US tax return. The US taxes dividends at 15%, interest and SS 0%. When I add 401k/IRA withdrawals, these will also be 0% US tax; still no requirement for me to file any US tax returns. But ... Ove is moving to Denmark, not the UK.)
The
US/Denmark tax treaty is
not the same as the UK one. It seems to be a complete mirror image, and for private pensions a bit of an outlier. Look down the "Pensions and Annuities" column of the IRS's
withholding tables for NRAs and you'll see mostly 0%, a few 15%, but 30% withholding for pensions paid to Denmark. The other outliers are France and the Philippines. For Social Security, the normal case is that the US gets to tax that; here it is the UK that is the outlier.
So, in the particular case of poor Uncle Ove, if he files the I-407 and ditches the green card, but has a US 401k or IRA, it does look like there may well be a lifelong requirement to file a wretched 1040-NR and get any overwithholding back from the IRS (with of course a long delay; let's just say the IRS does not prioritise 1040-NR returns). That sucks. It seems I over-generalised the normal case to this particular one in my
previous post; sorry. If Ove gets only US SS payments though, no 401k or IRA, and no other US income besides perhaps interest and dividends, there should be no need to file any 1040-NR, since the tax withholding on these will match the US's standard rate on SS payments made to NRAs.
If there's at least a partial silver lining to this, it is that if you have to do it, then filing a 1040-NR is usually pretty simple for most NRAs. You only have to list your US source income, nothing else goes on it. Two or three pages will pretty much cover it. Copy and paste next year, with slightly different numbers. Done.

And if US tax withholdings equals US tax liability for NRAs, then I want that system for citizens too!
Unfortunately, it'd never work out for you. Unlike NRAs, your non-US income all factors into your US tax liability, and the US has no say, or even any realistic visibility, on your non-US earnings, dividends, interest, and so on.

You know I just didn't want Ove to be burdened by excess withholdings on US sourced income. If that is not the case then yeah I agree abandonment is best.
It's a cost-benefit decision.
Not surrendering the green card may still leave some level of overwithholding, because the US has withholding rules on payments made to 'US persons' abroad that sort-of ensure they cannot easily underpay tax. And in that case, Ove would have to file full 1040 returns every year, declare and perhaps pay US tax on Danish bank interest, local dividends, local pensions, perhaps local social security, and deal with FBAR and all of that nonsense. All without any effective right to live in, or even visit, the US. (If you think it morally, ethically, and perhaps constitutionally indefensible that the US would seek to fully tax someone who has no rights to residency, visit, or vote, no argument from me!)
Surrendering the green card (assuming no threat from the US's savage expatriation tax) gives Ove the 1040-NR treatment described above. At worst, simpler and far, far less invasive; at best, zero, no need to file anything. A trade-off though for potentially larger US tax overwithholding, and potentially also a higher overall tax burden, depending on the difference between local Danish rates and the US's rates for NRAs, and the nature of the payments Ove receives from the US (SS, 401k/IRA, both, dividends, interest, and so on).
That's US tax for NRAs for you, I'm afraid. Never simple, never straightforward, never clear and never unambiguous.
