You will support Elon Musk if he creates a stablecoin and then pays 1 Million $ to each user every day? Do you even know how the economy and the market are working? You can not just create Billions and Billions of Dollars out of nowhere because that would generate such a huge inflation that all the money would be worthless. Also if everyone would be a millionaire then the world would stop to work because then there would be no more people that would do all the dirty and work that is necessary to keep he planet running.
That being said, i also support Elon Musk because he wants to make twitter to a place of real free speech and that is very important in my opinion.
I would guess "printing" money and generating money are different things. If he somehow earns more from the world than he pays, that would be possible to do without needing to print money.
We all know of course he won't be paying that much money, but lets assume for a second that he prints 100 billion dollars, and sells it, and then he decides to give 8% return on it, first of all that is 8 billion a year extra, and he already sold 100 billion dollars worth, so he could use that added money to make an income, and the rest from tesla, twitter, spacex and many others he is making profit already, so could he do it? He might but we all know he won't, that would be idiotic.
