Liberterians such as myself, would like to see a more prosperous world. With the technology we have available today, we're 1000s of times more productive than we were millions of years ago, and yet, 99% of society is still stuck working 40-60 hours a week and barely earning enough money to get by. There are many reasons why this is the case: taxes are only 1 reason. But, most of these reasons ultimately have something to do with government. Housing and Healthcare is no-where near as cost effective as it could be, if we were allowed to zone it properly and innovate on it.

Ultimately, Libertarians stand for the freedom of people. Currently, when a government takes and uses 1/3 of every dollar earned, the society is not free. Note: that ratio would be a lot higher in expensive areas like the bay area, etc.

1/3 doesn't sound like much oppression, but when you add in the multiplicative effect on the spending side, it becomes more onerous because everything is more expensive. The day care has to charge 50% more, etc.

It's about Maslow's hierarchy of needs. Most people, 99% are still working on their bottom tier. It would be morally, ethically, and economically wrong to stop their progress, by taking 1/3 of their productive efforts.

As the above posts mentioned, we do differentiate between natural resources and earned resources. Natural resources like Land should be taxed because you didn't create it from your own labor. On Earnings However, if you make your bed in the morning, you should be able to keep that labor - no one should be allowed to come over and use 33% of your bed.
