Someone will start pushing telescopes up there, with fast Internet in space why not have good telescopes up there as well. For cheap, not like Webb.
The cost of Webb wasn't the launch but the telescope itself. Folding it up to fit in rocket cost a lot extra but it would still have cost billions. The Hubble-sized Nancy Roman telescope, with much gifted by NRO, is going to cost $3 billion. The extremely large telescopes being built on the ground are almost as expensive.
It might be possible to build and launch a bunch of say 1m telescopes cheaply. But "someone" would need to fund it since it isn't something that company would do.
