My understanding is that there are several perpetual motion machines patented so while ideally you do have to fulfill your requirement:

"In order to patent something, you have to reduce it to practice. That is to say, you have to actually make it work, in the real world."

In reality you do not, otherwise there would be not patents for perpetual motion.

"Literally, I am tired offending the trolls."

I do not think you are dealing with trolls in this thread. Believing so will probably only block you from understanding and possibly convincing your the person on the other side.
