We could just create a crypto currency where we just hand out 100 units to every person.
Not without a trusted central party you couldn't. The work that goes into bitcoin mining is the 'distributed engine' that prevents double spending or forging of bitcoins. Bitcoin mining is not just a way of handing out new coins, its the very engine of the whole system. The only known way to break that engine is to control a bigger engine of the same spec (the >50% attack), and thats looking increasingly unachievable by anyone.
