As far as I see, your proposal is well-defined and consistent. However, even if we ignore all the intractable problems with translating it into any practical answers about concrete problems (of which I’m sure you’re aware), this is still only one possible way to aggregate and compare utilities interpersonally, with no clear reason why you would use it instead of some other one that would favor and disfavor different groups and individuals.
I agree with you that my proposed scheme is computationally intractable, and that it has other issues too. IMO the other issues can be fixed and I hope to get feedback on a completed version at some point. Assuming the fixes are good, we’d then have an unimplementable specification of a way to fairly balance the interests of different people, and a next step would be to look for some implementable approximation to it. That would be an improvement over not having a specification, right?

The implied principle here seems to be that if we can’t find a unique way to balance the interests of different people, we shouldn’t do it at all. I believe there are multiple plausible schemes, so we will be paralyzed as long as we refuse to pick one and continue. There is precedent for this—many cultural norms are arbitrary, for example.
I wish I actually had multiple plausible schemes to consider. I can think of some with obvious bugs, but it doesn’t seem worthwhile to list them here. I could also make a trivial change by proposing unfair weights (maybe my utility gets a weight of 1.1 in the average and everyone else gets a weight of 1, for example). If anybody can propose an interestingly different alternative, I’d love to hear it.
Also, if I incorrectly extracted the principle behind the parent post, I’d like to be corrected.

Analysis paralysis is one path to defeat.
