I agree that some use of force is necessary, however that is the fault of the majority of people. Many people donate to charity willingly. If the country was sufficiently amazing, if the politicians weren't so corrupt, if the government wasn't so huge, if we weren't taxed to death to pay for its profligacy, then maybe more people would voluntarily donate to the State, especially if society appreciated and celebrated noble voluntary acts more than they currently do, rather than the stuff you see promoted during pride month.
“If Men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and the next place, oblige it to control itself.” -- James Madison
