Answer 1

Money makes it easier to barter with.
It is difficult for any one person to be their own plumber, doctor, dentist, farmer, construction worker, woodwright, metal wright, chemist, ...etc.
We have to barter to get those things we can't get or make ourselves. Money is so that we don't have to find other people to barter with, but rather, can buy what we need easily.

Without incentive to acquire a skill to barter with, most people would probably be quite lazy.
