There are consequences to liberalizing things. This country has been on a steady slide toward less puritan behavior. "Good!" most would say. But the evidence suggests that when you liberalize society you pay a price. "Puritan" laws, while seemingly onerous, do promote a more decent society.
I'd be hard-pressed to say today's society is better than the 60s/70s I grew up in. What's changed? A million things like this law... drip, drip, drip. Call me an old fuddy duddy but the results speak for themselves.
I once read something that said something along the lines that "maturity is learning to deny your immediate wants either for others or for your long term desires". Like wanting to go to the bar every night or you want to hunt/fish 24/7 but now you have kids... or you want a house or better job in the future so you practice discipline and work hard and don't piss your money away.
In my opinion, less rules/laws that promote some sort of common discipline and order or otherwise deny people from having everything they want when they want it is resulting in a bunch of adults with a maturity level equivalent to what grade schoolers had in the 50s/60s.
Will the elimination of this blue law be noticeable on a social level? Probably not, to most, but it's just one more drip in an ocean of change I've seen in my 50 yrs in ND. #$%^&>
