There is no such thing as a "right to basic help". A right is derived from man's capacity for rationality. This capacity means that man is free to choose what he does and does not do. When you speak about a right to basic help (or healthcare, or education) you speak of taking away the choice from the provider.
No rights are conferred by forcing another to act. That's theft.
That's a subjective judgement. The right to property is not as simple as the right to free speech. Because my right to free speech does not stop you from having yours. But the fact you own a piece of land, prevents me from owning the same piece. Property rights can't be all black and white.
there are charities to do this; most of America's richest people are its largest givers, and this was true even before it was tax-advantageous; ie Rockefeller, Carnegie, Duke, etc.
The difference is, it was voluntary.
If charity was enough there would be no needy
This has little to do with the concept of a system of laws that protect individual rights.
True, this is utilitarianism, thinking about what will happen, to people, instead of some kind of kantian rationalisation of what you have or have not to do.
