This is probably a controversial opinion, but I think we should be careful what we wish for. Death is a necessary part of life. Without it, society will stagnate, overpopulation will become even more rampant, resources will become more scarce, and dictators will hold power for unbounded lengths of time. No. The controversial opinion is saying that death is unnecessary. Your opinion represent the 'mainstream' opinion. I would argue that it's status quo bias, or justification and rationalization for having death. Humans are very good at justifying things after the fact. But taking a look at the individual objections, it either falls apart or a lot more complicated than you think. For example, the fear of societal stagnation. I think this is an overblown concern. People are always changing, however slowly and imperceptible it may be. An 80 years old is going to think very differently than 8 years ago. People are always worried about overpopulation, but you know who pollute the most? Rich countries. The richer you are, the more meat you eat, the more 'resources' you consume. Currently, overpopulation is really about pollution than running out of raw resources, such metals and minerals and energy. We would overheat ourselves before running out of space. Obviously, there's going to be a finite limit, but that limit is so far off that it's basically ludicrous to think about. Dictatorships holding power for unbounded length of time? Sure, dictators might live forever, but it's clear that their society often basically 'stagnate', more like went backward. If you see North Korea and South Korea, you know that South Korea have more lights. Plus, just because you're a dictatorship doesn't mean it's a stable governing structure. There are dictatorships and military junta that are short lived or had been overthrown. Dictators can blunder into serious strategic mistakes, like Mr. Putin. Some even voluntarily democratized, like Taiwan! Human societies are inherently dynamic system that changes over time. It would be difficult to imagine a system that somehow managed to keep things exactly the same. There's always room for disruption.
