i'm an anarchist. you're probably not. but, you need to know when to step away from your need to control things, and this is one of those situations.
the science does not support bans on travel, or bans on large gatherings, right now. i will not be heeding these restrictions, myself - and i fully expect to get this virus, and defeat it. i don't want to cower in fear of one another, i want to take this on headfirst, and develop the antibodies. bring it on!
i hope that i can lead by example.
but, i will strenuously avoid old people, and i will state this clearly - if you are in an at-risk category, you need to take responsibility for your own safety, which means staying inside, even if you're not sick. if you're going to ban anything, it should be the movement of retired people. stay home, granny.
i know you want to help, and that's natural, but if you want to help then you should follow the science.
the only worthwhile thing you can do is avoid old people.
