I assume that's because Archlinux is designed to be minimal and you to add and change things. You are expected to understand and people maybe experiment or do things wrong. On top of it, the ever changing nature of always up to day can break sometimes (usually it doesn't, but its more prone to breakage than a cyclic upgrade).
My above suggestion wasn't actually using Archlinux directly, but more like EndeavourOS or CachyOS in example. Arch was just an example, there are also Rolling Release models for Fedora and openSUSE as well. I just mentioned this type of Rolling Release as to why you would want to switch off from Mint, as this could be a good reason for.
