Independent living buildings and Covid 19; any thoughts?

My mother 86 is living in a small independent retirement building {80 apartments} for the past 8 weeks. The building has common halls, common lobby etc. We, the family caregivers, are given temp checks, wear masks to go in and fill out paperwork every time we enter the building. What I find interesting and scary is these old folks can get in their car and go into the community to shop despite being delivered meals to their doors 3x a day plus snack delivery 3x a day! They are not restricted. Virginia has a stay in place order until June 10. My mom has hooked up with an old boy and he goes to shop at Food Lion and then goes in my mom's apartment and spends hours with my mom who also says they sleep together! She has known him 4 weeks. My brother and I order groceries online and have stayed very isolated for weeks to protect her. So we protect mom but she is exposing us potentially to the virus! That really makes me angry. She feels she is old enough to die but appears to not care about us. We are in our 60’s. I have talked to her numerous times. She has some dementia but has many clear days and hours. She can discuss the virus. We are considering an assisted living move for her. It appears she can not make good decisions. Any thoughts?
