Cost. Same as them fooling carbon dating, electron microscopes, isotope analysis, and a host of other techniques.
Forgery has always been about how cheaply you could make fakes, vs. the odds and consequences of them getting enough scrutiny to be identified as such.
It's one of several techniques they can apply, at least. I for one don't even know why there's a forgery market for ancient pottery, or that there's a market for it.
