It was a thing 10-20 years ago already. Civilians paid for a trip (on the Soyuz iirc) and got it. It was just very expensive.
This flight is purely for paying customers, organized and conducted by a private company. If there were enough paying customers, SpaceX probably would be happy to have such a flight every month. With this mission, space travel has become something you can commercially book, though at a very steep price - that might come down with the Starship.
