Yeah, well just because you've never experienced a different way, doesn't mean that there isn't a better way. And no one is saying abolish taxes completely (though that would be nice) we're saying abolish income taxes, which punish hardwork, and when coupled with the welfare state reward sloth, laziness, and spendthrift behavior.
Alternative systems such as Tariffs (which was the way the government was funded before the Federal Reserve and Income Taxes) can be used, and provide an incentive for companies to build factories inside the country to avoid tariffs.
Then there's the National Retail Sales Tax (FairTax) which would replace the income tax with a sales tax and require a much smaller, efficient IRS, because the number of collection points would shrink from 200+ Million to a few million or even less, as the government would only be collecting at retail sites. It would also result in the government being less invasive in people's lives.
Of course, the FairTax would cause problems for the Fascist Police State, because no longer would the government be able to violate the 4th amendment against search with out probable cause, and thus individuals would once again be secure in their property, papers and homes from the tyranny of the State.
There's also the aspect of the fact that the income tax is an immoral system that is similar to slavery, because it is collected using force and coercion, (a trait that it could be argued that Tariffs would share) unlike the FairTax which would be voluntary, because people could just not make purchases if they wanted to save their money free of taxes. It wouldn't punish hardwork, thrift and accumulation of wealth and thus would ultimately make it easier for people to build up wealth, and start their own businesses. Which would increase the dynamicism and resiliency of the economy, and allow for more people to migrate from the lower and middle classes to the upper classes.
