Ethereum switched to proof of stake, which dropped the energy used by the network by 99%.

Well, proof of stake is less power hungry for sure but it also has a big con : The people who control most of the currency can now fake money. Considering our capitalist society with very big gaps in wealth, this is not an acceptable thing.

A lot of bitcoin mining is already done with renewable sources of energy.

That’s not great. These sources of energy could be used more productively. There’s also nonetheless tons of it is done on coal.

Blockchains are public ledgers. They are terrible for avoiding taxes!

Public ledgers which do not contain the information needed for taxation - pointless.

There is a lot of overlap in the culture of distributed centralization and federated systems. Many people that are into Bitcoin are really into the fediverse too.

There is some but I think most people who want a distributed system will go for a distributed social service like Aether for example.

There may be “good” reasons to block someone from making transactions, but who gets to decide what is good? like you said, sex workers should have access to financial transactions just as much as any other worker.

The people should through the government that establishes regulation. I don’t believe workarounds to be solutions to these problems. After all, a sex worker can still not solicit work through social media and would be unlikely to look for help from the government if they need it because their work is prosecuted. Cryptocurrency does not solved that.

I use Bitcoin and Ethereum to store my wealth. From my perspective it solves the problem of needing to trust someone else with my money. It’s not unheard of for banks to fail and take your money.

Again, I believe in the government needing to bring good laws to solve these problems. I don’t believe that deregulation solves these issues. I also think that you have to trust an infinite number of people to trust in a blockchain system, people who are not regulated by law.
