In contrast every aspect of the Falcon rocket and Dragon capsule design was determined by SpaceX. NASA set the overall goals and safety criteria, but you can see from the differences between the Starliner and Dragon designs how much scope the manufacturers had. It really is a completely different paradigm.
It has been done before; for example the Thor IRBM was a competitive bid between Douglas, Lockheed and NAA. Official specs specified the equipment to be carried but the bidders designed their own airframes and launch facilities.
Douglas only won the contract to do the airframe and integration. It looks like a typical arrangement of the era. It’s not as if competitive bids have never been part of this process, they very often have. That’s not the point at all.
Sure contractors have been involved and built lots of components, but this is the first time a corporation has owned the fully, complete product as well as the facilities to launch and recover.
No company does (including SpaceX)
They don't own the land like they do with Boca Chica, but from the operational perspective they are the same.
Leasing the pad also prevents SpaceX from making certain modifications and puts some infrastructure constraints on them
Space launch is also heavily regulated. SpaceX isn't free to launch anything. Every launch is subject to tight government controls on everything from the technology involved to the specifics of the range. Nobody is going up without US government permission. Their ability to "do" space tourism is not that different than previous space tourists on other rockets. That a corporation is selling the seats, and the passenger lists then being vetted by a government, rather than a national government doing both is again only a legal distinction.+
