I have undertaken a lot of research around this. What you are saying is correct but will be a slow approach. Upgrading the grid is a critical component for transition to happen at a pace that will be fast enough to meet reduction targets.
What we need is a large amount of private investment into utility scale renewables. To unlock this private investment we need a stable market and a predictable floor to the wholesale price. Connecting all states with a high voltage DC grid and the creation of industrial hubs in regional areas will impove the feasibility of peak use industries and battery storage. This provides the above mentioned stability and price floor.
Without the grid most projects would need to use behind the meter production. Making energy a capital expense and not an operating cost.
