It's not infinite. It's just obligation for the end of life. It's not that far from obligations for the real-world businesses to clean up after themselves when they finish operation.
What's dumb is that now businesses can infinitely sit on a piece of real estate they no longer use, at no cost to them. If that was real estate not IP they would at least have to pay property tax on it.
It's kind of curious that businesses don't pay property taxes on IP, like at all. That might have really improved the ecosystem.
