Others have as much right to what you have as you do
Cooperation is necessary to resolve issues of who controls what
Second reason
You live in a society of other humans and beings
They have rights just as you do
You must respect those rights willingly or be forced to do so
Third reason
Much, perhaps most, of your lot in life is due to luck
If your luck is bad, you will need help; the same for everyone else
The more universal the willingness to give this help, the better your chances to live a good life no matter what happens, and the better the chance for everyone to live a good life
Life is hard for everyone, not just you; let’s take care of each other
