Yea but that creates downward pressure in the shares too, so there’s a natural limit. Elon could just keep buying more and the market value of the company won’t change. If it did change I.e. you could issue more shares without changing the value of the asset you could just do that all the time from the standpoint of the company and raise infinite money.

So it’s a question of balance. Twitter can raise the fundamental value of Twitter a little bit but there’s no way they can raise it too much without driving the price down and then just having more shares available at lower prices, so like you could just buy 2 shares and spend the same amount of money.
