The fact there are certain things the government is responsible for and need tax dollars to pay for is not and never has been in doubt. The problem with Sanders and others like him is they think everything a person wants but can't provide for themselves the government is supposed to do it for them.
It all exists on a continuum. The big mistake the current Right has made is in its absolutism - inferring, even saying, that all government is bad.
That has very helpfully allowed the Left to point at government services that most people want and say, "see, they're wrong."
The current Right is as responsible for any move to the Left as anyone else.
