but I'd have to first run a random blob I refuse run because there is no way to verify what that blob does
There's always reverse-engineering... an option which I believe could be far more powerful, and Stallman should've argued for; the ability (and right) to figure out what some software does and modify it is the fundamental key to the freedom he argues for, and while having the source code can certainly help, it's not the only possibility.
The power of RE comes from the fact that, while it's very easy to not release source code, it's nearly impossible to prevent someone from reading the binary on a general-purpose computer regardless of what the legal situation is.
I don't know what you're advocating for here. The ability to reverse engineer is explicitly required by the LGPL, and the GPL necessarily requires a minimum standard that covers the RE-ability of any covered work...
