How it could work Taxless society:
Tax works for us if spent wisely by the government. We try to pay tax the lowest possible amount legally that's why we keep receipts of everything we think that can reduce our tax. Now if it will be a taxless society and a minimum tax will be taken from an annual basis that government has no control since its Crypto, what will happen to government projects, infrastructure? It will take more time for it to finish because of funding.
It is my opinion that most governments are simply too big, most governments are getting a lot more taxes than what they need to pay for things like infrastructure or services like the police or firefighters, right now governments are trying to redistribute the wealth, but that is a futile exercise because their attempt to do so is really inefficient since most of the money that they get for that purpose is consumed by the government itself and the infrastructure they have created to redistribute that wealth.
