Net metering doesn't make sense for a simple reason:

- when you use power, the grid is forced to produce it for you at that specific moment.

- on the other hand, solar panels produce energy at random times, regardless of whether it's needed or not.

Net metering forces symmetric pricing into a fundamentally asymmetric situation, which is not scalable.

You could think of similar asymmetries in other contexts where the unfairness is obvious. Imagine making a deal with a restaurant for them to deliver pizzas to you whenever you order them, and in exchange you'll give them back the same number of pizzas at a time of your choosing (or at random times). This is obviously not a fair deal for the restaurant.

Your analogy introduces factors that aren't present in the system, I dont think you need to use one here. Solar panels arent exactly random for one, pizzas arent fungible for two, and the grid is already composed of many producers and consumers for three.
Energy as a service isn't fungible either. You can not trade energy at one point in time with energy at an other point in time and expect both to have identical value. There are many energy speculators which trade is to determining when prices are low or high, and with good weather predictions its not that difficult to make a accurate guess about the price a few days ahead in time.
How does that make a pizza restaurant a better analogy than just the situation itself?
Analogies are terrible but I’ll bite—

Imagine if you will there’s a peak demand for pizzas (dunno maybe Super Bowl?) and the pizza company is struggling to deliver enough pizzas. You come in and say hey Mr Pizza Company I’ll help out with that demand and make pizza for you, and so will my other neighbors and we’ll help you supply pizza. Mr Pizza Company takes your pizza and sells it but only pays you a fraction of what they charged their customers. And on top of that charges you for making pizza for them. This is what you get in return. Except you’re making pizza everyday and giving it to the pizza company so they can sell your pizza out in the market first before they sell theirs. The greatest trick played.
