Ah but, then, if you bought game licenses through STEAM, you download the games. And STEAM enables you to make backups of the games that you rightfully own. So that means you can have 10 copies, AND the unlimited STEAM installs you can make (there is no counter) and you're set for life!
Provided STEAM/Valve don't go out of business. At least with the physical media, you're not screwed because 2K Games files for chapter 11. I think STEAM is absolutely unbeatable to protect your games asset.
The whole point of the article is that protecting your "games asset" is pointless and ultimately futile, as it only inconveniences legitimate customers, regardless of which draconian protection scheme you're using. Do you wonder why console games outsell PC games by huge margins? Because console gamers don't have to put up with stupid pointless software like STEAM.
