No. As a general rule with all software, you purchase a license to use the software, not the actual software itself. That being said, GOG and Itch.io can’t yank games that you’ve already downloaded. I don’t know if Steam does or not, but it probably can.
It’s hard to prove the blanket statement, “there are no good reasons to have a private jet.” But it’s easy to prove, “one overpaid person taking a private jet to commute 1000 miles is frivolous.”
