Elon is always going to be dealing with the "but where does the money COME from?" issue because he owns Web2 properties.
"We'll charge $8.00 a month and try to sell people on the idea that we are letting them 'EARN' back some of it with their content!"
People without sufficient brain cells to crunch a few numbers will probably fall for "because Elon said so!"
Maybe he should try paying content creators in fractions of twitter stock...
