Here's a question I have:

In a blockchain world the government will be unable to track transactions. Correct? They won't be able to know how people are making money or know how much money people are making.

So how will they collect taxes?

They can't.

And if the government can't collect taxes the government goes away.

So a civilization run by blockchain requires a civilization that can run autonomously of government.

Tell me if I'm missing something.
