If they search around for an answer to that question, pretty soon someone is going to tell them to "self-host a Mastodon instance" or in the near future "self-host an ATProto instance".
My point is that the term "self-hosting" is unlikely to get them what they want, unless they happen to be interested in learning about DNS, IP addresses, ports, port forwarding, routers, firewalls, NAT, CGNAT, TLS, TCP, HTTP, web servers, Linux, updates, backups, etc, etc.
I don't think "web hosting" is going to help them much either.
What most people want is something like a Mastodon instance from masto.host[0] that integrates with a service like TakingNames[1] (which I own) to delegate DNS with OAuth2. I think we need a new term for this sort of setup. I think the term should also include self-hosting solutions, as long as those solutions focus on the outcomes (having a car to drive), not the implementation (building a kit car).
