Your point about community is valid, we need community.
I would argue though that digital community is a tenuous definition in comparison to in-person community. I won't claim this doesn't differ person to person but for me doing a hobby with people has no comparsion to watching youtube videos about the hobby (even though I am introverted). I like to consider to myself: "is this digital interaction preventing or taking the place of an in-person interaction I could be having right now?" 6 hours of youtube a day was preventing a lot. Further I considered my own hobbies which themselves were primarily digital and may be unhelpful for finding fulfilment in social aspects of life.
