Nobody is able to speak for other people. This just doesnt work.
Its just laziness if people prefer to have others speak for themselves.
Anarchy is the only system where nobody can hide because "it was not their decision" and where nobody has the right to "decide for other people".
I mean, are you good at gifts? If you dont know what a person wants to get as gifts, how do you want to know exactly what decisions they would make?
