I don't think it'll blow over as easily because the PS6 is going to be as expensive as a PC[0], at $1,000 or more. The usual things that inhibit consumer action are hassle, expense, and inertia, and Sony is dishing out all of that to its customers already.
What PC are they going to get for a comparable price, that also has a disc drive? The Steam Machine came out more expensive than they wanted due to the current component price crisis and doesn’t have a disc drive.
And even then, where is anyone buying physical PC releases?
The disc drive itself is not relevant so much as what it represents. On a PC, you have much more freedom even without a disc drive. On a PlayStation, without a disc drive, you are fully at the mercy of Sony 24/7.
