“It does, l’halacha. What do you mean, “let it”?”
Halacha has not established the “going rate”, unless the anonymous rabbonim behind the $2000 claim on SYAS are “the established halacha”.
“When you say, “establish”, do you really mean, “to publicize”?”
No, I mean establish. As in each community should institute what is considered an acceptable range normal range. There are takanos for everything else, rabbonim can institute a takana for this too.
