[N]o ideal form of anything exists anywhere.
I disagree, as it's certainly possible to construct an ideal form of something in one's mind.
The problem I see with that is that if there is an ideal, that implies one. So if you ask everyone you ran into to imagine the ideal random object, I bet you wouldn't get two alike.
It's like religion. One of the things that always bothered me was that God's Word shouldn't fracture into all these thousands of sects and their disagreements and so on based on cryptic snippets written down eons ago. It should be like 2 x 2 = 4.
