It's easily actionable: if you can't pay the dollar, don't listen to the music.

(Or, ignore the advice, if you disagree. That's fine too! But that's not the fault of it being non-actionable).

Kinda silly since buskers usually perform at places where people are usually anyway (such as a train platform) and I can't turn off my ears.

"Hanging out somewhere where there happens to be music played" is quite different from "listening". The advice only applies to the latter.
