The answer shouldn't be that astronomy has to have smaller, less efficient and slower built space telescopes that cost up to 100 times as much as ground telescopes. Size matters for telescopes and there's a limit to what can be launched. Whilst Hubble provided amazing insights it can't replace all ground telescopes. Additionally ground based telescopes can be fixed and upgraded without the need for an astronaut to be flow to repair it, a capability that doesn't currently exist.
