I understand what you are saying which certainly applies to art, so if you view HB and FA as artists and innovators the point is taken. But if the point is not to eat the food, what is the point. May as well just display the wonderful techniques and creative plates in a museum and forget about paying to eat it. Buy it for your walls. Since I can't do that I will still try at least one.
But you're providing only two extreme alternatives, faijay. The "point" lies in the middle.
Between food scoring 10 for deliciousness and zero for innovation and skill, and zero for deliciousness and 10 for innovation and skill, there sits a fat duck
What Blumenthal does, I believe, is apply his innovative drive and skill to the objective of producing something that scores anywhere between 4 and 8 on the deliciousness scale, balanced by 6 to 2 on the innovation and expression-of-skill scale.
I have now had several three star meals which only score 4 on the deliciousness scale an yway, and they're still zero on all other counts
My own preference is always towards delicious, but I am happy on occasion to sample "reasonably delicious and very interesting" as a valid culinary alternative. I doubt that I would go for the Extreme Eating represented by El Bulli.
