I don't use tmux but I use screen which AFAIK is the same basic functionality on my Mac. I use it to run long lasting software during development, so the frontend and backend of the service I'm developing for example, since they have hot-reload.

It's not _necessary_ but it's nice knowing I can close my terminals without worrying of having to wait for another 10m build because I like to keep my open windows to a minimum.

I think it's really down to how you use your computer more than a real need.
