For every person like that there are more people who aren't. The unfortunate thing is those who are as you say more cavalier are the ones getting all the attention (maybe rightfully so) or putting the attention on themselves and those who are using precautions are not really talked about.
Discussions with extremes don't normally help the rest of the people because the people who are like that aren't likely to change their tunes. I've never seen anyone on the Boards at least advocate for just going to town in their town all willy nilly to the heck with it all
So much of people discussing social distancing do it in a way as to say "stay in your home don't come out" but that's actually not what is being recommended nor meant by social distancing.
"The CDC defines social distancing as it applies to COVID-19 remaining out of congregrate settings, avoiding mass gatherings, and maintaining distance (approximately 6 feet or 2 meters) from others when possible." This for some is being applied to "stay holed up in your home don't come out". It does mean certain places like malls, theaters, etc where there normally are groups of people within close contact aren't the best at the moment.
It doesn't mean "don't go to the park, don't leave your home, and whatever you do don't step foot in a store". Take precautions while you are out about absolutely, including washing your hands (like normal) when you're out touching things and use wipes or sanitizer if washing your hands isn't feasible.
These definitions of course may change but as of right now that's what they are.
