Bathroomcoffee, if you don't know thousands of people works at the industry related to nightlife. How would that affect them.  There are many relatively poor people works in that industry.

Second thing is, Many people working in particualrly big companies works whole week and in  the weekend they go out and enjoy. I am sure more than 95% of peopel going out at night have no intention of fighting . They just want to have  good time. You cannot curb their right to have a good time.  What kind of Draconian rule is that you stop their right just for the shake that our police is always incapable to restrain few rowdies.

Real reason is the maoist were always against the nightlife . They used to collect taxes from the clubs before they come to government.
