> web 3 = own

1. How would this work for me as a user? Are web 3 "websites" (or whatever constitutes a service or company) not able to retain a copy of my data? Or phrased in another way, what prevents websites from also /owning/ my data?

2. How would this work for me as a service? Aside from my service's domain and internet address which are annoyingly hard to "own", what else is there to own that I don't already own?

I don't share hn's irrational hatred towards crypto so I'm not against joining whatever web3 is supposed to be (in principle) but I've yet to be shown a single benefit in doing so.

Give me a single clear benefit to using or offering a web3 service.
