The goalposts are shifting massively here lol.
The point is that a Blockchain is public. You can put an entry into any database you want but if it's not public people can't see it. Blockchain is literally just a publicly visible and trustworthy database.
How will blockchain prevent this without a team of lawyers to sue the crap out of anyone that tries?
Wut? Are you serious? Do you think there's like a company out there called Blockchain that hires lawyers or something?
If you owned something on the Blockchain and someone else tried to use your image for profit you'd hire a lawyer and take them to court. In exactly the same way messi would???
Wow.
C'mon man. It's fine to not like something but intentional ignorance doesn't look good on anybody.
