This is a pretty tough scenario. Its hard to imagine a situation where there is a significant amount of self-hosted bitcoin AND the dramatic price difference of your hypothetical.
As you note in your disclaimer, the permissionless network is one of the major value propositions of bitcoin. So it's kinda mentally difficult to imagine it both exists AND has no value.
Maybe a question that gets at the same idea (who's here for number go up) is what would you do if bitcoin forked to add in some kind of massive block size increase or transition off proof of work and all the etfs go with that fork and so price goes up for the fork the day it goes live? Poll answers could be: sell gov't fork, sell bitcoin classic, keep both.
I fully agree, this is an extreme hypothetical. I could actually have rephrased it completely differently and with a much simpler yes or no question.
Do you accept to take 1 billion dollars to never use Bitcoin again?
Just thought it more fun to do it this way and provide a backstory... albeit a very unrealistic one.
EDIT: your suggested question indeed achieves a similar goal.

I answered that I'd keep my self hosted btc but it was entirely an answer in denial: there's no way that shitty captured btc is worth as much as my free range sats!

Haha, at least you're being honest that if this scenario ever happens, you'd entertain, if ever so briefly, the idea of - what fiat-maximalists call - cashing out.
