Ok, sure. There are theoretical and convoluted ways to disconnect from the electric grid. You're still buying solar panels. Your out of pocket costs don't change. The river of money still flows into and out of your life. It's called currency for a reason. The whole system is designed to stop you from keeping your money.

The dark secret about money is that it only works when there's isn't enough for everyone. Despite what politicians want you to believe, you are SUPPOSED to live paycheck to paycheck- at least under a western capitalist economy. This is why poor people are both the most valuable citizens, and easiest to control. It's slavery with more steps.
