That argument has been harder to make with time. A couple years ago I made the difficult decision to get rid of some old game copies. I wasn't realistically going to use them ever again, and the sentimental value for me is entirely about the memory, not the media. Part of my steam collection is nearly as old and it is on track to greatly outlast. It is also significantly easier to own and use in just about every aspect, even if it is technically just a revocable license.

Beyond that, Steam and the digital media model allowed a great many people to publish games that wouldn't otherwise have been able to publish games. It made the indie world of games possible. It also did more than anyone to bridge the platform gap between windows and linux.

I'm really worried about what will happen to Valve when Gabe retires.

I can see a bean counter making a very convincing case that it's cheaper to go back to Windows and avoid all this Linux reverse engineering gubbins which isn't bringing in an immediate profit, especially when they're giving away all theirs efforts by open sourcing Proton.

Is that how things work at valve? I thought employees do whatever they want and there's minimal structure.

Gabe allegedly (nobody knows because it's a private company) owns 50.1%, it's not majority employee owned. It's possible he might turn it over to the employees or some kind of co-op style board but who knows if he's offered the right price by a cashed up investor.

He's got children to consider and could reasonably want to set them and his grandchildren up for generational wealth.

Which just further highlights the importance of actual DRM free ownership. Even in the face of a relatively benevolent corporation, that corporation won’t be that way forever. Leaders and cultures change, sometimes overnight (look at what happened when Broadcom bought VMWare, they started extorting customers immediately). Adobe is another good example that pulled the rug out from underneath creatives and started renting software instead of selling it.
