The goal of the storage industry is not to take everyone off grid. The goal is to increase the penetration capacity of intermittent renewables. You can get to 50% penetration without storage, but you need demand response and storage to push beyond 50%. So, most storage isn't priced to be off-grid, it's priced to provide the most value to the consumer (demand response, peak shaving, backup power, etc.). At the end of the day it's all about economics, and there's lots of economics in favor of connected storage in addition to off-grid storage.
