Libertarinism would also hurt jewish relgious life in America
One of the unsung reasons why Yiddishkeite was able to flourish in the US was laws to protect jewish observance and the 5 day work week. Prior to the 5 day work week it was very hard not to work on shabbos and leaving early on Friday was not an option
Yeah some people did manage to get fired every week, but those people were really few and far between and most at a certain time eventually gave up.
Without laws protecting your rights, You could be fired for leaving work early on fridays or not working on Saturdays.
