So are the two biggest problems with geothermal just the depth of the crust and having to build the infrastructure, or is there something more?

They also have diminishing returns on energy production because unsurprisingly, pumping water into the ground cools it, eventually.

Another problem is that if you have to pump the working fluid too far down to reach the heat, you'll have difficulty getting the hot fluid or vapor back up efficiently.
