I think your living in fantasy land if you think there is a way to prevent everyone in the country from not interacting with people outside of their family. Which is what a strict lockdown means to me.
Well given your abject failure at the concept I'm not surprised you think it's a fantasy.
Personally I've been basically hanging around my neighborhood for months but that's about it. Still some of my neighbors have construction jobs so they have been at work and in contact with people throughout this entire quarantine, and my kids hang out with their kids all the time. So anyone they're parents have been in contact with then I have too by proxy. That number starts to get incredibly large.
