"In a fully free society, taxation - or, to be exact, payment for governmental services - would be voluntary." - Ayn Rand
"In a fully free society, taxation - or, to be exact, payment for governmental services - would be voluntary. Since the proper services of a government - the police, the armed forces, the law courts - are demonstrably needed by individual citizens and affect their interests directly, the citizens would (and should) be willing to pay for such services, as they pay for insurance." - Ayn Rand
Convince us we need the service, show us that it is being run properly, and people will pay. The same thing should apply to all taxes - including property taxes (real estate and personal property), state income taxes, etc... So long as there are any mandatory taxes, we are slaves and own nothing.
How does that work with police and military? It's seems like there's a large incentive for people to free-ride, saying they don't want/need the service while benefiting from other people paying for it.
