Morals talking time.
However, objectively speaking, taxation
is theft. It's taking someone's property without their consent, and it is compulsory. It very much fits
the definition of theft, even though you can find it slightly altered in other sources, like
the Cambridge dictionary ("the crime of
illegally taking something that belongs to someone else")
Lol...I can't stop laughing here cause I don't know which angle you are bringing this from and what it tends to justify. You have to know that a country's affair is a serious affair, it's not what social reasoning (moral is not the right word as used) can take care of.
"Tax is never a theft and never will it be regardless of how you may interpret it." I can only advise you to accept the tax of your country in good faith or protest so that the government may reduce it if it is too much. Anything that is in the constitution and the law of the land is binding and must be obliged to as Rights. Therefore, tax is the Right of the government, citizens have theirs too.
This is what is helping the country, otherwise, everyone will do as they like and there will not be a country fitting to live in because there will be broad daylight theft and anarchy since there is no means for the government to empower and operate security architectures in the country. That is one reason among countless reasons. Or do you want the government to work for the people while they pay nothing? People will not even be efficient about this if it is voluntary, so what will be the general state of the country?
I summarily conclude by saying that tax is good but must be justifiably used. There is no way the government will tax anyone if there are no purposes for it. Also, the government can't tax you if there is no law backing it. By virtue, I don't see this as "theft" in all ramifications but a "compulsion." Where there is a law, there must be obedience to it.
