Why force people to help others if they do not want to?

If you want to help people, a good idea is to open a business, or to become a Capitalist. A Capitalist, in this instance is differentiated from the businessperson by having Capital which is made available, the Means of Production, so that it may be exploited by the workers for profit.

We can, almost, be sure of doing no harm if we are either a Capitalist or a businessperson since we always allow people to refuse without imposing physical harm. We are not a protection racket, or the Mafia. The only possible complaint against the Capitalist (against the businessperson there are none, unless they commit a generic crime) might be that they are in possession of too great an extent of the means of production, but this complaint is more effectively addressed at those who uphold the property rights, usually the Government.

We are even more helpful to others if our service is offered at a reasonable price.

We can only be doing harm if we prevent another person from doing what they want to do, or if we seek to coerce others into doing what we want them to do. If we do not feel an obligation, a debt to others, then none exists. There is no utility in imposing, forcing others to help the community. Being forced to do good will lead to resentment and is (to suffer from) a form of tyranny.

Forcing others to do good will not result in good outcomes and will lead to harm, and even violence.

The taxpayer is forced to provide Government Services for the rest of the community. We are forced to provide for others, but why?
