Republicans have been talking about shrinking the size of the federal government for decades. They routinely fail to come up with substantive cuts in spending that would not set off a disaster for them at the polls, or for the country economically, or both.
There is this perception that the federal is full of wasteful spending, but this perception is false (there is waste, it's not a large percentage of the huge overall federal budget). This means that to actually cut the revenue needed will require truly substantive cuts to the services provided and performed by the federal government.
Maybe you could be more successful at proposing what those cuts would be than any Republican has for 50 years, but it seems unlikely.
While there are certainly people who believe as you do, you are not in a majority. There are also a lot of people in Argentina (possibly a majority) who don't agree with those policies either.
