If the purpose of Tesla is to accelerate the transition to sustainable transport, then its purpose depends on the utility industry transitioning to renewable energy.
Renewable energy cannot supply the grid fully without storage.
People will buy more model 3's than Power walls.
The model 3 should be grid interactive. (for both charging and discharging) It has an inverter - how hard to make it output to the grid? (well, almost no one has 3-phase at their homes). Or perhaps just a DC output made available to an existing inverter suffice.
This would make the transition possible, while right now, it's just a dream waiting for new technology to arrive.
