Yes, we need roads, we need fire fighters and some of that stuff. However, it should all be financed privately.
So you propose making the 'gap' between the haves and the have-nots into a wall. No ambulance is coming to help you...because you are poor. Your house is burning to the ground...because you're poor. Your children will be doomed to a life of abject squalor because you are so busy scraping and stealing to feed them that you have no time to educate them, that is, if they don't die of pertussis or rubella, because there is no vaccination program or standards without taxes.
I advocate a peaceful transition from the current system to a system based on cryptocurrencies rather than cash transactions.
We have allowed ourselves to become dependent on the political system and thus on evil itself. Obviously, if we would lower the tax rate overnight, there would be massive negative consequences. Hence, that's not the way to go about it. But if every individual increasingly starts trading in BTC rather than USD, we will slowly be able to reach new ground. Bit by bit, bitcoin by bitcoin we will exchange an involuntary system for a voluntary one.
Eventually, the BTC system will be valued so highly, work so efficiently and be worth so much that it will not be much of an effort to buy out the public infrastructure. There is in fact nothing stopping multinational corporations from maintaining infrastructure, they have shown in the past that they can administer very complex systems, i. e. there is nothing that the public sector can do that the private sector cannot, rather the contrary.
