Challenging yourself against nature is a valid way to appreciate it; it can help you humble yourself and get in tune with your body and build a connection to nature.
Nature does not have to be a shared experience to be valid, doing stuff by yourself is an ok way to experience nature, too.
You’re being pretty judgemental of how people like to enjoy nature, when you should be encouraging people to enjoy nature.
That isn’t solarpunk.
You’re saying being by yourself in nature is being isolated from it? What are you on?
Going into nature is not inherently a shared experience, that’s just objectively like, wrong.
Also you know hiking and climbing and those things where you challenge yourself are usually group activities anyway, right?
