OP, there are a lot of artists doing beautiful work with jade plants. Just google "Jade Bonsai" and you'll see countless examples.
I get what folks are telling you here, that jade isn't really a bonsai plant in the classical sense. That said, delta blues slide guitar isn't really guitar in the classical sense. But the old flamenco-pickin' spaniards of yesteryear probably would have really gotten a kick out of it and would likely have experimented with it if they'd had metal strings and beer bottle necks for slides.
By the same token, the old Japanese masters (who would have been seen as a bunch of rebellious upstart wannabees by their Chinese Penjing predecessors) would probably have gotten a kick out of working with jade if they'd had access to it.
I've done a lot of "bonsai" on jades. I think it's taught me a fair bit about styling, potting and how to focus on plant care that will be useful on my journey toward becoming a decent bonsai artist with "real" bonsai trees. I've just recently started to undertake some serious classical bonsai with real tree species. I don't regret having played with the jades first and continue to enjoy doing so. Jades are good for a little quick gratification while we wait patiently for our real trees to progress. It may not be "Zen" but it's kind of a hoot. :0)
