noob friendly linux idea

tldr: i want quick saves for linux.

I was thinking today about how when i started using Linux it was a huge pain. Nothing ever seemed to work, I would install things, then go to use them and get hit with 'command not found' not understanding why, and it was frustrating. The worst part of the experience for me though was that after several distros, and unsuccessful attempts I had finally gotten Steam running, then I went to bed, woke up, ran sudo apt update because it was the only command i knew really. went to play a game, and steam wouldn't work. i searched for hours for solutions, not knowing the right terms to use, getting mocked by members of the community, getting frustrated with linux as a whole and nearly saying 'screw it' and going back to windows. but i decided to give it one more chance and for like the 15th time, i plugged in my usb drive, and did a fresh install. went through the exhausting hours long ordeal of installing the apps i wanted again, then again finally got steam to work.
Almost gave up, but my stubbornness prevailed, and 4 years later i run linux on everything and it's awesome! But, today i thought about what it was like at the beginning and i had an idea. what if user sessions weren't real? like, what if each time you logged in, the system made a new user environment based on whatever older session you picked? If that existed when i was starting out, I could have been way more willing to use the command line, willing to just try things and see if they worked, and when things broke i could just load an older session before i screwed everything up. i know there are ways to do certain types of snapshots and backups, but what if it was built into a distro? so at login the user just selects which save file they want to load? i don't really know what all it would take to implement something like that, and i really just want to get people's opinions about it. idk if it's something i'd be able to try and build out myself or not, but i feel like if it existed, maybe people who are new to linux wouldn't have such a hard time if they didn't have to start from scratch every time they do something dumb.
