A third option is to train with a gun buddy and buy one when you feel it is definitely needed. no major financial burden, and you get firearms training.

Some hikes shouldn’t be done alone.

Also this seems like it’s gearing you towards selfish thinking which can set you up to be more isolated and lonely as a person.

I gear towards joining in things that others I like the company of want to do. I get to hang out with them while doing some activity, and they get to enjoy that activity. Of course, if I’m going to invite someone to something, it’s most often going to be something I can enjoy myself. If it requires others I just check with my friends on who’s interested and do followups with them to reduce barriers and increase their chances of making it.
