That's a self-fulfilling prophecy. People generally prefer to stay legal as long as the money is reasonable and the friction to use what you've fairly paid for is sufficiently low.
Meanwhile, we're talking about Microsoft "letting" us do something many of us are already doing via emulation. Gee, you bought a physical disc rather than a worthless digital entitlement? Sucks to be you, pay again... Except... Yeah, I really have no need for this new option when the old one is still superior.
And to be clear, I'm in no way talking about actual piracy. I've paid for a looot of media over my lifetime, and quite often I'll still use a "fixed" version because it's in every way the superior product.
