Wait what about the middle ground? Give me access to a VPS and I can make your dreams come true, as cheap as possible, using modern CI tools and a lot of.. automation.

Perhaps. But it still takes time. And a level a of expertise. And what happens when you want to go on vacation? Get hit by a bus, etc.?

Once you do the math it becomes a break even at best. Once you factor in opportunity cost, managed hosting for most WP projects is a better fit.
