I think you're out of your mind if you don't think a lifetime license is practical.

The default license for almost everything, including software, is lifetime. I do not pay Ford an annual fee to advance the timing of the ignition sequence when I need to accelerate into traffic. I do not renew a subscription for the thermostat on my wall every winter when I need to put it in heating mode. When I was young, I bought a license for Epic pinball from then Epic MegaGames. I still have a license to that & can still enjoy it.
