In Speedcubing the point is to solve the cube with techniques you know. No inspection would make more advanced techniques completely useless because that takes time. Look ahead would be trash and it would be impossible (almost) to be color neutral. In the Red Bull speedcubing Bill Wang, a color neutral solver, used white cross only in "Fastest Hand" because there was no inspection, making it very hard to use his full skill and potential. Let's take Tymon Kolasinski, one of the best 3x3 solvers in the world. He relies on inspection to plan amazing solutions. His 3.43 Full-step Sub-WR single on ML had a xxxcross and a pause less 4th pair. In a following interview he said that he planned the entire F2L solution during inspection. Think about how crazy that is, most people struggle to plan an xcross but the entire F2L, the hardest step of CFOP! To say that solve would have been more impressive without inspection, maybe a 7-8 second solve is ridicules. If inspection was to be removed it would never have been added in the first place. Sure, there are some debatable rules in the WCA but inspection seems like a no-brainer. Speedcubing isn't about pleasing the spectators like in say, American Football. It's about doing the best you can do with the skill you have, if you want to please the spectators with a less impressive solve with lots of pauses for the average cuber by turning down inspection, go ahead! No one is stopping you. But to argue that it should be removed because you think it benefits not the joy of speedcubing is ridicules. If inspection was not a part of speedcubing I wouldn't partake in the sport because it takes the joy of striving to improve away.
As mentioned in another post, solves would be completely based on luck, not skill. There would be countless variables that take away from efficiency and such, CFOP would be pretty much the only viable method besides LBL and we'd have to go for the first thing we see. Inspection on the other hand is something that you can never stop improving with, you learn and learn, get better and better, and maybe one day be like Tymon, even he is continuously improving. All the skill is to know what to do in each situation and how to take advantage of certain positions. With no inspection you simply don't have time. You can say you work it into the solve but it would be better just to get right into solving then to make a massive pause to look at each individual piece and determine what you can do best with what you know.
I think you should have an understanding of the cube, methods, techniques, planning, etc, before you make a conclusion that it would be possibly better without those 1-15 seconds and, no offense, but with what I can garner you do not have a mediocrely advanced understanding of how to take advantage of things and how to plan multiple moves ahead in a short time.
Just my two cents.
