What would you say is the value of decentralization?
I think that in reality, PoW systems become more centralized over time. You can already see that with Bitcoin. Eventually the gatekeepers become those with the largest energy resources available to them, and "we the people" will be in the noise when it comes to hashing power.
I'd rather take energy efficient centralization than faux decentralization that also happens to destroy the environment.
It's not healthy for a society when people start self-censoring their actions like that. If nothing else, it places banks in a privileged position where they can get away with more predatory behavior, because people are more likely to see them as a necessity.
It's for this reason that anonymous transactions are valuable. You really should be able to buy legal marijuana or books about firearm construction without worrying that people might judge you. Neither is illegal, if you want one (or both) you should have the freedom to purchase them. However, many people would choose not to buy them, simply because they know the bank might see it on their balance sheet if they ever have to call the support line, and they're worried about follow-on consequences to their insurance premiums or their job if knowledge about that purchase ever circulates. That's a chilling effect in action.
On some stuff you cannot put a price tag - like mastercard ads say, some stuff is priceless.
