Another semi-aside: The term "censor transactions" needs to be abandoned, because it accepts the whole "money is speech" nonsense at face value.
I'm willing to begrudgingly accept "money spent to effect speech is speech" but no further. The vast majority of crypto transactions do not fall within that narrow bucket, and using the word "censor" to refer to reversing them with a 51% attack is propaganda.
My understanding is that when people say Money is speech what they really mean is that it is a human right.
When an authority freezes your bank accounts (like Trudeau/Freeland did to the truckers) they infringe on your other rights (right to property, right to shelter, right to assembly , etc) demonstrating how much of a slave people are under these regimes.
When a payment processor cuts you off without recourse, they also infringe on your rights.
Money that most people know today is a terrible way to store value as it is also a tool for the state to control them.
Ethereum is now another government tool since a great percentage of transactions are validated within the US jurisdiction and are thus subject to the same draconian laws as federal bank issued money.
