Bruce, your points all address your own musical tastes and tendencies. That's fine, but the fact that you've chosen a musical path which excludes some things which others may wish to embrace is only that; a fact about Bruce Lindfield. It's not an argument for abandoning anything. It's not an argument at all.
...everything was informed with musical sensibility...
So wierd noises are OK, as long as they are informed with musical sensibility?
I don't think we have anything at all to argue about, if that's how you feel. You seem to have arrived at conceptions of what "wierd noise" is that are entirely different to mine, and probably to those of the originator of this thread.
When I think "wierd noise" in the context of a music discussion forum - as opposed to a natural history class where I would expect to hear talk of elephant noises

- what comes to mind is soundscapes, unusual use of reverb and delay to create texture, notes shaped oddly in the tonal sense, sounds growing and morphing over time, adventurous harmonic feedback, reversed and treated sounds, and so on.
In other words, very musically useful sound - stuff you could layer over the top of a slow ballad and have work musically. Or over the top of a demoniacal rock breakdown - let me cite Radiohead's Bulletproof and the end of the Smashing Pumpkins' Silverf*** as respective examples.
I think you might call that music, Bruce, and I'm pretty sure that it's the sort of thing our thread instigatee Stu Hamm Rules had in mind, too, whatever the semantics may be.
Basses are designed with music in mind - it just seems perverse to use it for another purpose - why not buy the right tool for the job?
I might answer that by pointing to a Mr James Marshall Hendrix. He made ALL kinds of sound with a more or less stock Fender Strat and a big amp - squeals, moans, airplane noise, wierd bubbly things, beautiful floating soundscapes - sometimes in the same song. Why didn't he just pick up a synth?
Because the guitar-plus-amp WAS the right tool for the job, for him, and thankfully as a result we have some crazy, fascinating, totally human music to listen to which certainly doesn't conform to what a guitar had being used for until then.
Why not do the same thing with bass? "Because St Leo didn't intend us to back in the 50's" doesn't seem to cut it as a reason, for me.
Incidentally, elephant acoustics are completely fascinating. They have an assortment of loud "regular" calls and also produce sound in the subsonic frequency range - these subsonic calls are designed to travel well by refraction through the evening or morning atmosphere. They can be heard many kilometers away - if you are an elephant.
