Some situation being the "entropic norm" that things tend to without intervention is not a good reason to prefer it. If we allowed everything that costs nonzero effort for the state to prohibit, we wouldn't have a civilization at all -- the ultimate "entropic norm" is pure anarchy.

So rather than arguing from these philosophical principles I think it makes more sense to answer a pragmatic and very concrete question: is the world would be better off, or worse, for having intellectual property protections? I think it's clearly better because the existence of these protections encourages people to spend time and effort making creative works (including software). That said; I think software patents are counter-productive, as are extremely long copyright protections for software. But I think that for pragmatic reasons, not abstract ones that seem to fall apart when you examine them closely.
