On destroying a legitimate career

I can't find the article concerning the original issuance, by Chareidi rabbis in Israel, of the recent ban on Jewish music concerts, but this article from Arutz 7 about an upcoming concert there contains much of the original language and response, to the best of my recollection. And this post by Rebel with a Cause informs us that some "15000 frummies [Orthodox Jews] attended this concert, ignoring the ban on concerts."

Blog in DM has a few words to say here. His key point: "The notion that someone can take away a person's legitimate parnassah [livelihood], let alone an entire industry, without addressing said loss of income and their responsibilities to those affected is bizarre, and creates a huge chilul Hashem [desecration of The Name]."

My "Simcha inflation" post addressed a similar issue: "If folks who are fortunate enough to be able to afford to do so don't buy $800 foot-tall sterling silver Chanukiyot [Chanukah menorahs/candelabras], will the lack of customers put a legitimate Jewish artist out of business? If a rabbi declares that having music at a Bar or Bat Mitzvah party is against the "sumptuary laws" (rules that attempt to eliminate the keeping-up-with-the-Yonatan's problem by limiting the amount of money that can be spent for certain things), wouldn't such a ruling deprive all the local Jewish musicians of dozens of gigs every year (in addition to depriving the community of the opportunity to hear some good music)?"
