Actually, it's not. It's been tried in all sorts of endeavors and eventually falls apart. Back in the day, there was a motorcycle series "Formula USA", with rules essentially "must have 2 wheels, no alcohol", and it was all well and good with folks running their hand crafted, bored out Superbikes until Kenny Roberts showed up with a pair of factory Yamaha Moto GP 500cc two stroke machines (which is, essentially, "unobtainium"), and, in time, dominated the field. Things like that lead to rule changes in F-USA. Also, consider the origin of modern MMA. The "Ultimate Fighter Championship", which was a "no rules" bout. Royce Gracie dominated those events early on. I will never forget UFC 4. Dan Severn, a very powerful wrestler, was dominating his bouts (3 as I recall). His fights were over very quickly. Meanwhile, Royce, who was a skilled grappler, while winning his bouts, they were taking quite a bit of time. At the end, Royce had just finished his 3rd bout and then had to stand up to Severn, with very minimal rest. Combining Severn's fast bouts, with Royce long bouts gave Severn a lot of time to rest and recover between fights. Royce was obviously quite tired going in to the final round. Severn dominated that fight, but it drew on...and on...and on. Over 15 minutes. In the end, Gracie prevailed, upside down, pinned against the fence, with Severn bent over him. It was an extraordinary encounter. But in the end, it led to rule changes. 15m fights don't really work with the broadcast schedule. Seeing two guys tangled in knots for 10m straight with minimal movement isn't very interesting to watch, either. And now we have modern MMA with combined striker and grappling skills. Turns out competition is only fun when it's fair. While its technically interesting to see folks exploit the rules, and even dominate, it's more interesting when they have to work within them. In the end, you (most folks, I know I do) want the man behind the wheel to be the deciding factor, not the machine beneath him.
