I’m interested in what “traditions” you’re talking about here? Honestly, it is not even clear to me what you’re talking about when you say “these” in your sentence. Certainly tradition hasn’t held that Rust memory management is an idea and therefore not patentable. Same with new models in ML? Maybe there is some tradition for protocols, but even those are generally patentable but required to be licensed via FRAND.

Your post seems to entirely misunderstand the patent system. “But one may not receive the protection of the government for [ideas] to give temporary advantage over competitors.” This is just flat out wrong. The purpose of a patent is literally to receive the protection of the government for your ideas in order to give you a temporary advantage over your competitors via a government granted monopoly on an idea. The bargain that’s struck is that the patent owner gives the details of their patented idea to the world so that anyone can eventually practice it or build off of it in exchange for a limited exclusionary protection in commerce.
