Because if one looks at the ideology of "government is bad, make it small, we will take care of ourselves" the embrace of government patent protection seems discordant.
From what you seem to be contributing here, I take it that you think, "government is bad except when I benefit and that part I support and there is no discord in that; next?" which is fine, your answer is admitted to the record. Other people may have other opinions and I am interested in them. Next?
That seems to be approaching a strawman argument.
I haven’t seen any reasonable argument from government minimalists that would say such a thing. The position is generally that too expansive a government can only restrict individuals. That government is needed but only should regulate where it is for the benefit for all society.
The biggest difference I see between those who believe that government is the answer to any perceived problem and those who believe in minimal government is their different beliefs about humanity and in government.
The “Big government” advocates see humanity as corrupt and in need of control. They see government as that control and have faith that politicians are knowledgeable, fair, caring, and compassionate.
The minimalists see humanity as being capable of working out minor differences without undue governmental regulation They see excessive government as a path to power and influence for politicians to use to benefit themselves and their friends and their interests.
I suppose the argument boils down to how one views humans, government, and what is "needed" regulation.
