You are ignoring the restrictions and regulation that exist around sharing data in lots of financial, government and medical industries. Sometimes, the missed cost of 5 percent accuracy is much less than the inspections, delays and blockages that otherwise would occur if they wanted to use real data.
I misspoke; I should have said, "I'd happily take the synthetic data."
But yeah, you're right; I was being oversimplistic in just thinking of it in terms of "can have/can't have" and not considering the, "can have, but at too high a cost" angle.
