The problem is that electricity is a natural monopoly which means it will basically always be a monopoly so the options are since the cost is too much for their to be naturally competing wires to your house:

1. have it be a state agency

2. have it be a monopoly but heavily regulate it

3. Have it be a Texas style market that guarantees access to the monopoly piece of the physical wires. Which has lead them to basically running out of energy how many times...
