This is a valid point, but the other side of that coin seems to be that - despite an incredible amount of work done on containerization and rapid deployment services - "click to stand up your own services" startups just... don't seem to succeed, at least not in any everything-you-need-on-one-unified-host way. The last company I saw trying to make click-to-deploy unified self-hosting work was Sandstorm.io, that became Sandstorm.org, that ... doesn't get a lot of traction.
