if the only way to use government services was to purchase either a dairy queen or McDonalds burger first that is a duopoly and they would be way more expensive and shittier quality than regular burgers as a result.

some smart alec would then point out that because even the cheapest, shittiest beef isnt free that this price is justified.

Nobody has said what Google is doing is justified. People are (correctly) saying that "taxation" is not the correct term for what they are doing. Google is in the wrong, but that doesn't make bad arguments correct just because they are aimed at Google.
