You can already buy a server or rent one with any of a large number of hosting companies.
Web3 is just a worse way of paying for it that enabled scammers, grifters and is unstable due to rampant speculation.
I am not advocating for web3. I am saying its some middle ground at a new shot to not give all your data to someone who says this will host your data for 'free' vs an easy (to be seen) way for my stuff to be hosted with some type of payment from me in exchange for someone not abusing it. I know that is a tall orders, but from what I have seen that is the pitch for web3.
If you want to make it even easier to control how your content is hosted, join one of the many open source projects that are building free tools that make things easier.
Edit: While I not the biggest fan of WordPress on a technical level, that piece of open source software has done far more to democratize the ability to host your content on a platform you control than the entire Web3 ecosystem put together.
