why would future humans bother bringing all these people back

i think it's worth reminding why doctors treat people now, in this time and space. they do it mostly because they want to save people. maybe a few do it for money, but past a certain point, the money isn't why you do it. i think it's a safe bet that doctors of a future would see these corpses as patients, and act accordingly. an analogy - think how we see heart attack victims as patients, and not how our medieval ancestors would have seen them (as corpses)

...literally nothing positive to contribute to the utopian future...

true, but, a good chunk of patients in hopsital today have nothing to contribute to society, and cannot contribute any more, whatsoever. we treat them anyway, because that's what we do. humans have consistently cared for others that are sick and have "nothing to contribute" throughout history, and that shows no sign of going away anytime soon

But why the fuck would future humans bother bringing all these people back, even if they could?

There are many valid issues to raise with this bring unlikely to work, but this point seems silly. Why would a road maintenance worker fix a pothole, he's not from around and will never benefit from it? Because it's his job he's paid to do, and he's not having a philosophical discussion about it. Whatever future lab technician will be just going to work in the morning as well, paid by their company, funded by the money the preserved people paid. There isn't much to it.

But it's interesting you said that future humans would kill these people because the preserved people are useless assholes. I'm not that sure you labeled the assholes right in your scenario. Your future humans seem ageist and elitist, thinking only they deserve to live.

There is at least one example I remember from the news of a 20-something girl with cancer being preserved, paid for by pooling money from the family and donations. Unlikely to work but she would have died anyway. So what did she do wrong that she doesn't deserve to be woken up, in your future where the technology is there?

"Why would a society bring people back to life when they [describes why you think they deserve to die]"

Happy to know you're not going to be solely responsible for bringing them back!

To answer the questions of archeologists, obviously

Ever read Transmetropolitan? It has a whole sub-arc on just the absolute lack of concern that a future society would have for this resurrection obligation/burden imposed on them.

Humans are particularly difficult to preserve because of the delicate structure in (most of) our heads.

Nonsense. We are just too big to be frozen quickly enough that no ice crystals emerge. Every living thing turns to slush if frozen normally.

Is this a thing I'm not aware of, or just a very strange typo?
