Because its absurdly absurd. Your philosophy would make EVERY action somehow affect someone else and thus would throw "Freedom" out the window in exchange for the security of loving big brother. As if such a benevolent state could exist anyway.
You act like government is the highest good in the world, almost as if it were a god, and you act like every person outside the government is evil, unless they worship it.
You are the thesis as to why "Liberal" has become synonymous with "Authoritarian" these days, and with darn freaking good reason. You want government intervention in every area of every persons life. The only time when you do NOT want government intervention is if it involves killing people or ticking off social conservatives.
Liberal philosophy would be good if it still meant what it did when Jefferson was using it. Now its just a codeword. And it is with the clear intent to take away liberty from each and every person in the country and instead make them dependent on the government.
And I think its hillarious how you think "Conservatives" are the ones who want the huge, bloated state.
TLDR: Its wrong to say that everyone who believes in freedom is either evil or detached from reality
