Your reliance on your readers to construct your argument for you strongly suggests to me that there isn't much argument there. Because its an exceptional reader who has time for such research -- if the point where there to be made, you'd be more convincing simply making it yourself.
I know zero about Joe Biden's position on crypto. But the style of this argument looks to me very much like FUD.
Just read the rest of my comments. They directly address your point. Not wanting to repeat things I've already written in this thread does not constitute avoidance of argument.
It is also very easy to discover what the public law Biden cosponsored less than a year later said about lawful intercept and cryptography.
I'd tell you, but I'd be repeating several comments I've already written on this thread.
