It could be better, it could be flawed in the same ways, it could be flawed but in different ways, or it could be worse altogether. Compare our current lives with someone a century ago. Two centuries. A millenia. Plus hey if you wake up and the oceans have boiled off, there's solutions to your continued existence then.

> I know for a fact that I will grow tired of existence.

I think that's the main part - ceasing to exist should be a choice. It wasn't one to be brought into this world, but inhabiting it and going out of it should be done on one's own terms and when having lived as good of a long life as one might want to. For some people that will be close to a century. For others that might be a thousand years. Who knows, for some it might be a million years.

If this is all thought experiments, why not? At that point, why even care about waking up in a capitalist dystopian hellhole? Might take a few centuries to overthrow them but it's not like that sort of life is the end point of humanity. And if it is, at least you'd know that for sure. Or maybe it's nuclear winter. Or something closer to a utopia, or at least something where everyone's basic needs are more or less met. Asking for guarantees doesn't work either way.
