Container or VM is a bigger commitment. VMs need root and containers need Docker group and something like docker-compose or a shell script or something.

idk it's just like, do I want to run to the store and buy a 24-pack of water bottles, and stash them somewhere, or do I want to open the tap and have clean drinking water

Neither of requirements are true on recent OS versions. Users have had the ability to make containers or VMs without special privileges for a very long time now.
