There's a difference between revolutionary artistic technique and "revolutionary" mechanical design. Really? You bring up Jaco in a discussion about guitar
design? What parallels exist between his technique and ironlung's idea for wooden frets? The thing with mechanical logistics is that they work on specific principles; artistic technique doesn't have any cut-and-dry rules for "working," it's just a means to express one's subjective creativity. So really, your comparison is a load of BS. And mentioning Leo Fender is likewise insipid since he made instruments with metal frets.
It's a matter of simple logic, not "creative inspiration that may not sit well with some other artists." And actually, I've seen quite a few in this thread who say the idea would work with nylon strings. So you must be complaining about the nay-sayers claiming it wouldn't work with metal strings, which is just putting 2 and 2 together.
