The underground is a countercultural movement, lauding emergent culture and fighting against the mainstream culture. Then it seems quite normal that this movement strives for distancing itself from the mainstream and uses almost illegal 'free places', as an agora. But the free place needs subventions and rules to survive.
Therefore, the main aim of this movement is rejecting any kind of profit, in order to focus on meeting with other people, an essential value. A few money, a few official recognition but places founded by enthusiastic rebells, always in search of new talents.
