If only everything in cryptoland was "only as secure as 3DES"...

I don't see why. If this is because you avoid "insecurities in symmetric
crypto", I just don't buy it. Otherwise, please explain.

And how do you propose to do that? You can't conjure up good quality entropy.
And if you don't trust symmetric crypto, you can't use that to create an
almost-random stream either.
