Technically, stocks are a form of Tokenization, nowadays, because of the advent of digitizing the financial markets for online trading. Been that way for years. In Web3, ownership would be in the form of NFTs or a Token reserved for ownership recognition that an entity (dev) would legally be bound to honor as such, with earnings and/or board voting power delegated to those who held the NFTs/Tokens measured by their overall percentage of ownership. I could be wrong, but I believe there are already a good collection of such examples on Hive of that very concept.
