Is saving the game from an early leak worth getting rid of physical games? I hope not.

As a PC gamer who has been basically digital only since the late 00s/early 10s? Probably?

But the thing to remember is that, like with DRM, the studios have this data. There are orgs dedicated to analyzing (and selling...) sales data that can detect the impact that Mass Effect PC being "unplayable" for pirates because of securom for the first week or so had on sales (anecdotal but... probably real positive). Because this kind of stuff costs money (well, less so for removing a disc drive...) and they aren't going to do that if they think it will hurt revenue.
