Both NEM 2.0 and 3.0 have serious issues, but for different reasons. NEM 2.0 was basically a early adopter's rich person's subsidy that heavily distorted the market, and NEM 3.0 does not have nearly enough subsidies to justify the cost unless you pay cash up front for a large system. (For the record, I am on NEM 3.0 and got such a system).

At the end of the day, the best case scenario is large scale renewable / battery storage to bring costs down as much as possible, and for those of us who want battery backup / solar can choose to invest in it, but it shouldn't be "the" solution.
