The new paradigm being proposed is just too radical for comprehension

No it's not - it's just pointless. And, once again, you resort to insults for anyone who seems tainted with professionalism. And, once again, you provide no factual evidence whatsoever to support your "paradigm". Or should we say, dogma?

Sal (the lemonade lady): back garden festivals do happen. I'm a regular contributor to an an annual festival/party in the large back garden of a friend in Sussex. Each year, several of us erect awnings, PA system, blankets, chairs, bar area, food area, etc., in the garden. The back porch becomes the stage and we set out amps and mics and a guitar, a keyboard and a drum set.

On the day, we put up a tall blackboard and provide a box of chalks. Those who want to perform - anything they want - get 3 songs/tunes or 15 minutes, whichever is the shorter and put their names on the board. The music starts at 2pm and finishes at 9pm, when we strike down the PA and gear and join everyone around a large fire. Kids play on swings and hammocks and table tennis in the front garden - where we also had an acoustic folk session this year - and everyone who comes, whether they perform or not, brings a food and drink contribution. The organisers themselves provide a huge amount of food and drink, and bring out a huge paella at 6pm for everyone to share. The party is by broad invitation only - simply because the space is limited to around that number. We get children singing with their parents or with their friends. We get hoary old folkies singing hoary old folk stuff - we get blues, jazz, classical music, comedy songs. We get complete beginners and consummate professionals - all playing for fun and completing the day. And we have a dedicated rota of people who do the washing-up, staff the bar - and run the PA and compere the afternoon (my job).

The next day, a few of us are back again - striking down all the awnings, tables. chairs, blankets, groundsheets...

This is not the only example I could quote. But - note this: we're not trying to shoehorn people into a "culture"; there's absolutely no elitism (which would be scorned); no money changes hands; it takes a huge amount of unselfish organisation - and it's immensely satisfying. And we don't need the Conrads of the world to make it happen.
