You need friends and political parties when you want to enforce your agenda on the world.
You find love when the world doesnt want your agenda. When the world wont accept you for who you are, then at least one person in the same predicament will be enough for you to feel at home and to teach you humility.
What self-absorbed monsters humans are. Rare is someone who is too pure for friends and love. Such a one appears as a hermit, asocial to the 'normal people' but he is just fully what nature intended and needs no help to be that, not what society taught him to be.
TLDR: relationships are for people who want to dominate.
