Telescopes in space could have better performance, because you are not limited by atmospheric conditions for your angular resolution. But you still need a larger aperture to increase your theoretical angular resolution (see the Rayleigh criterion), and increase light gathering power.

Can't you have a fleet (something like StarLink, but telescopes) and have a bigger effective aperture?

[HorstG]

Theoretically yes, through interferometry. But that is really difficult when there is relative motion within the constellation such as with starlink.

For radio we might be able to make it work. But we currently don't have the ability to position satellites to within 10 nanometers, which would be required to make this work in the optical range that you have just killed off on the ground.
