I don't think a lot of people get this. These "space tourist" companies don't have an end goal as space tourism. The problem with launch vehicle companies (launch PROVIDERS) is that they don't always have something to launch (provide). To sustain your company you need to launch often. Rather, to sustain the low price on your vehicle you need to launch often.

You also need to get to a high TRL for confidence from contractors. People are more willing to take risks than someone sending up $100m+ satellites or vehicles. Those successful human missions get you to a TRL 9 pretty quickly.

But many of these companies have much bigger aims than tourism. Tourism is part of it, but more like orbital hotels, lunar hotels, etc. Not a short trip. But also mining. There's A LOT of money in mining once the vehicles get cheap enough. Which they aren't if you're flying a few times a year (like how most things come down in price when you manufacture at scale).

Nit pick: The point of the ride isn't to get 0 gravity. IT IS TO GO TO SPACE! That has a value much higher than that 5k 0g rides. Sure, 0g is part of it, but that's not why ANYONE is buying a ticket.
