I think the friction is a much bigger issue than the cost. People are stuck in a trap of scrolling short form video because it provides no friction. While organizing a picnic is extremely high friction relative to social media scrolling.
I think to solve this we are going to have to blow up social media and make going out in public more convenient and friendly. Otherwise we are going to end up in a WALL-E society where people spend all day with their meta glasses streaming AI generated micro dramas.
I don’t think money is a barrier to getting out.
