Ideas may also require intellectual labour. But one may not receive the protection of the government for them to give temporary advantage over competitors. Ideas are a collaborative venture, protocols being the very epitome of this - since a "protocol of one" is a bit like a birthday party for one... a bit sad and pointless.
If one wants to make money, by all means invest time in pursuing patentable inventions, but do not presume that mere ideas (most of which are "nothing new under the sun") should be afforded the same protection.
The problem we have today is that the patent system is derelict. The goalposts have shifted to allow almost all and any silly idea to obtain a patent and the system itself is weaponised for extraction. It has not shown any will to reform, so abolition may be its ultimate fate.
