First reason

• No on has absolute ownership of anything
• 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
