Since loop devices are limited, and based on of my ubuntu 18.04 (with cinnamon), one must assume that at some point ubuntu will be useless. There will be so many loop devices for the snaps that will pass the max limit (not mentioning that some apps, like gnome-calculator, are already using more than one). Is that correct?
EDIT (after commented):
I am running a default Ubuntu installation, which means that snaps are default for Ubuntu. (I am not sure, but I don't remember installing all these snaps)
The idea of proposing to desktop users to change the hard coded loop limit is out of (any) discussion.
