Steam isn’t always DRM, and even with its DRM, the vast majority of those games have continued to work without repurchasing them for over 20 years now. The premise at the top was basically that people are willing to give up the ability to resell their games when competition on PC has led to deep sale discounts, and I’d agree with that as well. On consoles now, you’re rapidly headed toward a future where you can’t resell your games and there’s no competition to drive prices down.
