It is significantly more expensive to put telescopes into space. And much harder to fix problems. Or upgrade. And more expensive to get the data. There are many projects which work just fine with ground-based telescopes. Observatories already work with nearby light sources to help lower light pollution or make it more manageable. For example, installing shields on the streetlights so the light is all directed downward, reducing sky glow. There's already a movement to reduce existing light pollution. https://www.darksky.org/ https://www.darksky.org/ .
