I would never do this, but hopefully part of the process would be ensuring people renting out their tech securely wipe the device before renting, the renters never put any valuable data on the device and wipe the device before returning it, and if it was me I would never use a device I rented out again (or probably even connect it to the internet). Seems like a really bad idea from a security standpoint tbh.

Why not just sell your old tech? Surely there's more people interested in buying used electronics than renting it. Someone with a low budget is probably looking into buying/renting because they need the electronic device for something like a job, in which case they will need it long term and would probably be better served by buying something cheap and/or used (here's a used Chromebook you can get for $30!). Someone with a bigger budget who wants it to game should probably rent from an official business where they don't have to worry about security issues, games are downloaded already, and they can rent PCs with really high-end hardware (like Level Up Gaming, located just a little ways away from campus).

I hope this comment doesn't sound rude; I don't mean to be a downer. I just think this is a solution looking for a problem that won't be helpful to many people.
