@steem.camp proved that money is not the issue.
This was the cheapest event possible; 30 euros for 4 nights of camping and food and drinks were paid with the ticket.
At the peak, we were 15 people, only.

This was the second time and the numbers did not change much.
I am aware, that I am not the most popular Steemian, but the main reason really is that people are lazy.
