Superconductors are themselves expensive, but are the cooling costs really that bad? I actually have another crazy idea for that.

Cooling cost require liquid nitrogen. It's expensive. That's partly why MRI scans are expensive and why storing cyronics bodies is expensive.

It depends on the scale you are working at. A large body with no internal heat source can be kept cold over time at a lower cost because only the outside needs to be insulated. If cryonics were at the scale of a large cryogenic warehouse, it might be much less expensive.
