Well, if taxation is theft and some taxation is needed, then you must be forced to conclude that taxation is not always bad, and therefore that theft can be good. This rather distorts the usual meaning of theft (though, like sh76 mentioned, in some cases theft may be justified).
But let's look at your alternatives. You correctly mention that freeload ...[text shortened]... cessary unless the private market is significantly distorted by cartels and/or monopolies).
I don't think we disagree too much.
Getting money out of people at all is difficult. Set the tax rate too high, and tax receipts can go down. So I think there is room to try out more positive ideas.
I think the honors roll for tax deserves a try. It would be among the people that contributory norms would spontaneously emerge, and informal public sanction can be as effective as formal sanction. I suspect the emergent norms would be fairer than the norms the government imposes. Moreover, the threat of reverting to compulsory taxation, if the scheme didn't work, would be an incentive that would push norms higher. I also think that people should be free to discriminate, when it comes to employment or providing goods and services, against people who cannot prove they pay enough tax proportionally: reasonable tax provision would be a marker or good citizenship, but on citizens' terms. Of course, I could be wrong too: for example, maybe the level of monitoring requires would be unfeasible. But I am only saying such ideas should be seriously considered, if taxation is theft.
There is also a lot of research in psychology showing that agency is intrinsically rewarding. So, if people were given some choice where their tax money goes, they would contribute more. They would make errors; but over time, the errors would diminish, as necessary public goods were appreciated. The government could also appeal for funds in emergencies.
I also think it would be as good to keep the government lean and eager for our money as it would be let it get fat and complacent. You'd get more for less. The government would have to make the case that it needed it to the people, rather than the people having to make the case for why they should hang on to their own money. This would hold government to account, a good thing. They would be public servants, not overlords.
