More broadly, if you live in NYC and know the NYPD, then of course they're going to respond in this manner when such orders come out. When they have authority, they use it.
Given that information, it seems that you would recommend people "shut up and stay inside" due to the "risk to other people". This is not rational.
Giving up everyone's freedom and accepting simple authoritarian solutions a few vocal people want is not a good approach. Punishing perfectly healthy people by threat of imprisonment as a result of the absence of planning by the nation's healthcare and government is not a reasonable response.
It's not primarily intended to tell individuals "you must stay home," just to strongly encourage that and make it easier for us to do so.
I doubt that. I'm in a mid sized city in WA and I've seen a notable increase in traffic in the last week. People are leaving their homes more now. Most of the offices are empty so I'm not entirely sure where they're going, but they're going somewhere.
