Exactly. Note that opposing patents on certain inventions doesn't mean you think the inventors don't deserve to get insanely rich by commercially exploiting them; it just means you don't think they deserve a government-backed protection to do so. So, what inventions should deserve such protection? For example, ideas which by their nature must be disclosed after a large investment in their development, but before having a chance to be placed in the market. Regulated industries like drugs come to mind. Even then, the extent of the protection should be limited to a (short) period to prepare and launch commercial exploitation of the idea. Therefore, the patent should include proof and plan for such commercialization of the idea.
