What? I have patents and written books, created products. If you are arguing for intellectual property, you are arguing against property rights.
What do you think of copyright, especially pre-publication? And trademarks? I think replicating someone else's mark is fraudulent (but I am not so sure that fraud should be considered a common law crime)
No. Ideas cannot be owned. Either you keep it to yourself or it’s everyone’s. Fraud is a different story. If you mislead someone into a purchasing contract that contract is void.
