I do see your point smallpiper and agree with you to an extent, but there is a big difference between a stage show such as Riverdance, where people are charged maybe £50 per seat, and a few friends meeting up in a pub to make music for their own enjoyment.
If they intend charging session goers for playing tunes etc, then perhaps we will see a time when music is driven underground as is the case with alcohol in Iran/Saudi Arabia etc.
