Yeah, I'm not (and never have) suggested there will not be a trade off... nor do I have a magic number of what that should be... there is a risk trade off with every life activity...
I also also NEVER said anything resembling that we should in any way "open up the economy with no restrictions".... that's every bit as a disastrous suggestion as the "lock down until there is a vaccine" crowd...
I said there needs to a balance... and that balance needs to start being employed on a case by case basis with common sense measures where they apply... before we reach a social tipping point.
Details obviously vary.... but the status quo can't remain much longer.
