I agree - it is about playing in a band, and maybe even being mates.
Make an assumption that you have it. Would you then be happy practicing with your mates even if they were 2 meters apart? Would you be happy if one of them got it afterwards, or one of their parents, and had a bad outcome, such as death or permanent injury, even if you couldn't know whether that was down to you or not? Would you be happy never knowing if it was your fault?
I wouldn't, so I couldn't do it.
I agree, part of the problem is people sitting in the park or scrums about bog rolls. The other part of the problem is people thinking that other people are part of the problem and they aren't.
