That's exactly how it works for politicians. When was the last time one of them was held accountable for fraud?
A "quick google search" answers that:

It is not the taxes in general that piss me off. Its that people are elected to congress thousandaires and leave millionaires. Yet they always need "more revenue." If you think you can fix it by voting, well voting gave us the Donald and it should have never come to that, and they will probably never allow it to happen again.
When people make millions working for the government, they are skimming off money that is supposed to be going to public services, yet they fly private or first class, representatives fly to foreign countries to look at dam systems. I mean, if this is the modern era like you claim, whats wrong with a powerpoint and teleconference.
AOC and Ted Cruz are actually working a rather unlikely alliance against allowing former congressmen/women from becoming lobbyists, which is one of the main ways so many of them gain their wealth from public office.
So there is some reason to have hope for the political system, even though as you mentioned, we have a very corrupt official who was elected president.
Roads are not and should not be the priority of the federal government. neither are police and firefighters. Local government and consumer taxes could handle all of this.
And local government/taxes do handle the majority of this. However, there is need of a federal police force above state law enforcement. Reasons for this can be found by looking back at much of what happened during much of the civil rights movement. In particular, just look at
Bull Connor.
The feds take between 18% and 24% tax on EVERY GALLON of fuel pumped in the US, yet they are on TV preaching how it is the presidents fault. Bullshit! It's our fault for allowing it to come to this.
Sometimes you need to tell your drug addicted child "no." The government is our drug addicted child. We created it, we enabled it to become a monster, and it needs to be told "no."
So here's my problem with libertarianism. It's the same problem that's coming from a lot of conservative media nowadays, which is that it's mostly arguments against things based on problems with existing things.
You don't like high taxes? Ok, that's fine.
You don't like government corruption? Yea, we agree.
But what *do* you want instead?
We can all agree that tax dollars shouldn't be wasted, should be kept as low as possible, and that they shouldn't be controlled by corrupt officials. However, just calling for and end to all those things is just replacing some problems with even worse ones.
Pointing out problems doesn't do much when you don't have any solutions and libertarianism tends not to have many solutions.
