you'd still need a way for the PC to know it was an original disc, not just a copy tho, and if the copy-protection related parts can't be read by a PC drive in a way that would distinguish them from a burned disc, there's no way of doing that.
and disc based protections, even for regular PC games are ugly, I notice as optical drives get cheaper and cheaper more of them become incapable of reading anything other than basic data, rendering a lot of copy protection schemes unusable even if pair with older hardware / operating systems that should be compatible.
real media compatibility makes a lot of sense on consoles, where you're always using known drives etc. and I do hope we see more of that, but for a PC based emulator I can't see it flying for any kind of commercial offering.
