Sure but the amount of maintenance for hosted is pretty small, if you pick the right host.
If you use something like Google Sites with your own domain, which is used by a lot of paying corporations, there's a good chance you'll never need to touch it again until you die, except for using some credit card information maybe.

There is really no "for as long as you live persistent hosting"
Self-hosting: ISPs change, people move house, power black-outs take servers offline
Hosted: providers change policies, are bought out, go bust, payment details change
