It seems like we should be able to build these things in space.

We can. They would be vastly more expensive than the telescopes we're building on earth, and uneconomical to fix or upgrade.

One day we'll have synthetic aperture radiotelescope swarms in space. For now, it's a better use of money to improve our earth-based systems first.
