You can't currently because we've not been able to grow sufficiently high quality crystals here on Earth with gravity. Basically anything that needs more than 30-60 seconds of microgravity can't be done anywhere on Earth no matter how much money you want to spend. NASA is already up there to learn about the effects on the human body (which again we can only really do holistically actually IN space) so trying to put the whole cost amortized over all the experiments isn't going to come up with a reasonable number. But even beyond that this is precisely what governments are supposed to do, gather and distribute costs that would make little sense for individual companies or even massive conglomerates to do.
