Stock ownership also gives you a payout. And yes you can use NFT’s for authorization, but you really don’t need to. That was already possible back in 2005 with some PHP. Although those systems were and still are often centralized and rely on the integrity of the infrastructure and the intentions of the people running it, you can’t host a service on the blockchain. Smart contracts can’t host a site. There still needs to be something in between the blockchain and the client.

I see the potential of a public ledger but most blockchain projects seem to simply use it as a marketing gimmick.
