It's about as simple to host a website on tor as it is on the clear web. As a benefit you actually own your domain name instead of lease it on the whim of some third party subject to external countries laws and political/social pressures.

Plus it has built in side-effect anti-DOS properties so no need to centralize through companies like cloudflare.

There's huge benefits to hosting on tor even if it's just a regular website. None of my websites hosted on tor are illegal in my country.
