Not everyone is an ultra extreme libertarian. By far most people want police, fire department, roads, FDA, FCC, OSHA, national security, social security, and even the DMV. And the system of taxes is something that achieves that.

People want those things, and they don't want the old Chinese drug dens.

Does that mean that the implementation is perfect? Absolutely not. Especially in the US. Mass incarceration is counterproductive and horrible. Cannabis illegality has a racist history. But personally I don't think people should be allowed to use fentanyl, meth, and heroin.

Even libertarians should recognize that there's no way such use doesn't have a huge externality caused by people who are judgement proof, on people who had nothing to do with the use.

Looks like you are an ultra extreme libertarian. And that's fine. But like anarchy I don't think it's a bad ideal, I just think it's a pipe dream.

How do you mean reversibility leads to increased consumerism? You mean because I wouldn't buy things online if my credit card wouldn't allow me to reverse the charges if it's a scam?

That sounds like capitalism, to me. You're free as a business to only accept debit cards. Debit cards don't (in my jurisdiction at least, and AFAIK most or all) don't have the same protections as credit cards.

Do you not like capitalism? This seems incompatible with the libertarian values you seem to have.

> Fraud protection could very well be kept under control and prevented with insurance,

I truly wish you good luck with that. No sarcasm. But I do also mean "yeah, good luck with that".

> instead of potentially invalidating every economic transaction.

Oh, you mean like the Ethereum DAO split? That was the true "socialism for the people who have connections, capitalism for the poor".
