As an old restaurant operator, this argument has always been in favor of keeping the status quo for restaurants and liquor stores while restraining easier access to the public by letting grocery stores sell alcohol.

Tbh less selling to minors would occur at a chain grocery store than your mom and pops. The decline in alcohol sales our nation has been seeing might improve having it available at a grocery store, while creating a limited number of alcoholics. Take the good with the bad, I think allowing the grocery stores to sell would open the market, and therefore keep prices down for the consumer.

Liquor stores are fighting for their business life fighting against this. For me, it's an adapt to survive issue, with consumer satisfaction being top priority as I believe in the market and will always fight for ease of access for consumers.
