So what happens if your hands (which you presumably use for programming) stop working and you are unable to do your job? Should you lose all your income, be kicked out of your house, and forced to beg for food? (And eventually get sick, not get medical care, and die at the age of 28?)

I wouldn't want that for you, and I wouldn't want that for myself.

Humans created a society for a reason, and it wasn't so that we could each keep everything we earn and have a slightly bigger flat-screen TV. The collective protects the individual from Bad Things that can be devastating for that individual, in exchange for a tiny bit of each individual's earnings. With that tiny bit, we can also build infrastructure that would be otherwise economically infeasible for a private entity to fun (or for each individual to build himself), but is beneficial to society at large. Roads, public transportation, the Internet, etc.

Assuming that everyone should live in isolation ignores basic human biology -- we are a social animal, and we need the collective.

The question is about how we distribute our wealth fairly.

The fairest method would be: Who creates the most wealth, gets the most wealth. The current method is: Who negotiates the highest salary (founders and passive income excluded), gets the most wealth. Basic income method: Everybody gets an equal little piece of the wealth, the rest is distributed like before.

It seems fairer to me, because for example moms are not compensated with the current system.

What do you mean "we've become"? Can you point to a time in human history where everyone thought they did not deserve a piece of someone else's stuff?

The early Christian Church, as reported in Acts - the believers shared all things in common. There was a brief breakdown when the apostles had to intervene as those distributing food to the widows and orphans were tending to favour their own people.

Are you rejecting the social contract entirely?

"No," says the man in Washington. "No," says the man in the Vatican. "No," says the man in Moscow.

Those men are correct.
