Considering the big differences between my world and this one? No, not all of them. Some of mine failed while people were gone for 5 years. Which is more of a there thing but businesses come and go anyway.
I mean, we're not all ACTUALLY strangers. It's impossible to not meet the neighbors when we're in this close of quarters and go through the things we do. Unless you hole up in your apartment and never leave except to open the door for delivery. But then there might be other issues to be working through if that were the case.
