Patents are for actual technical implementation, not ideas for things which would be nice if they could actually be built. I don't get a patent for imagining how great it would be to have pizza delivered by slingshot even if no one has thought of it before, and even if it delivering pizza by slingshot turns out to revolutionize the world. I have to actually invent the slingshot capable of delivering a pizza accurately. And if that invention is obvious for a semi-competent engineer ("Put pizza on big pannk stuck in the ground. Pull back plank and release.") I won't be awarded a patent.

Now, I can agree that it's conceivable that there could be a benefit for allowing such ideas to be patented. For instance, I've always thought that it would be convenient to have a foot-pedal to turn on your kitchen sink so you didn't have to use your hands to turn on and off the water while you washed dishes. In my imagination, the everyone would immediately realize how great these pedals were if a single company started to produce them. And, in that case, everyone would enjoy a huge boost in utility.

However, there's no way for me to capture any of that surplus because I can't patent a foot pedal for a sink under the current definition of a patent. If I started a company to sell these foot pedal installation, and it became popular, a million other companies could enter the market and sink me. And, all things considered, it's probably better that way.

Every hospital I've ever been in has foot pedal operated sinks on the way into the OR's. Most of the gizmos either have a patent number or a pending etched somewhere on them.
