It am happening a while ago. Feel bad for nice lady that am inviting me. Like I said, am probably explaining point badly. It go like this: In oversupplied market, it am essential that artist am maintaining dignity in order for audience to be taking them seriously. Without dignity, artist am unable to command respect or mebbe set high prices. Value exist in eye of beholder, and eye of beholder am being amenable to marketing and branding.
However, if product am available for free, payment-optional, then it am difficult to be establishing value higher than zero. It free, after all and "free" am other way of saying "worthless."
Discord people am then protest, saying that busking for tips am time-honored way to be making artistic living. Am countering with two points: Firstly, despite skill and effort involved, street-performing am still high-effort form of begging, and begging am not dignified. Secondly, performing on street am fundamentally different from posting content on Internet. In former case, artist am interacting directly with audience. Mebbe more importantly, natural flow of busking am geared toward paying. When organ-grinder monkey come around with hat, it take effort not to be giving donation. Latter case am totally different: natural flow of online consumption am to be moving on without disbursement of funds.
Unfortunately am being kicked out before having opportunity to explain second point.
