What does being hackers have to do with it? Every tech company and startup is already relying on the threat of violence to get what they want. They all use IP law which is enforced by the government and that enforcement leads back to violence.

Progress is not in the absence of taxes. Progress is in a fair and efficient use of the taxes money.

>What happened to the idea that we could apply our intellects, reason, logic, and rational thinking, and improve on the old way of doing things?

There are powerful groups of people with intellect, reason, logic, rational thinking but also have large sums of capital and the government's servitude to counter anything we try to change.

"how do we fund the things that are currently funded by taxation, which are actually necessary / desirable, without using violence or the threat of violence?"

Firstly, set up a gradually percentage-based system of mandatory contributions, based loosely on income, to be one's expected annual payment. Add in a unhealth dose of special-interest initiated loopholes. Next, split the whole entirely in half so you fall under an entirely different system if you earn your money working a 9-5. Finally set up a section of the government dedicated to enforcement of these statutes, with financial and penal penalties for violation.

I think the whole premise of your question is wrong.

Most countries have a fiat currency. The government via the central bank creates as much money as it needs to run a society, money is there simply to get things done, it's a promise to 'pay' for work.

Money in itself doesn't have any intrinsic value other than the fact that everyone collectively agrees to believe that it does.

The government doesn't have to tax anyone, it can just continue to create money and inject it into the economy and things get done. The problem comes that the more money it injects the less the perceived value of the money is (i.e. inflation). It needs to destroy some of the money it creates and it does this via taxation. That's why you have tax.

I'll get back to you on that question once you've found a way for people to "protect their assets" that doesn't also rely on force or implied threat of force...

If you frame tax law and its enforcement as violence and taxation is theft anyway, how do we finance a society then? How about YOU start answering the question?

Oh spare me your pseudo-moralism. If you don't think leaving people to starve to death or (insert obvious consequences of rampant inequality here) are a form of structural violence then you're just being a giant hypocrite. Private violence is a thing and you know it. Until you're willing to acknowledge that truth I'm not willing to waste any more time on your sophistry.
