Please don't romanticize isolation. We have enough elderly folk existing in dire loneliness in assisted-living facilities and nursing homes who understand the true definition of it.
as is often pointed out, loneliness and solitude are two different things. The latter, especially in nature, can be a very formative and restorative experience.
People aren't allowed to enjoy something because other people don't enjoy it? Other people are experiencing something they didn't choose, so nobody should be allowed to choose it?
You can "isolate" in less isolated places.
Also what's the point if the activity you're describing is linking through other people anyway (just over internet).
