Well, if the changes create more grid instability then pushing for more of them sooner leads to more grid problems. Another example: political pressure lead Germany to shut down operating nuclear power reactors when wind and solar weren’t ready to take up the slack. This led to a large dependence on Russian natural gas and…well, you know the rest of that story.
You’ve mentioned roads a couple of times. Roads and the electrical grid have significant differences. You can pave County Road A with only minimal impact on County Road B. Traffic can back up on the road to your favorite vacation spot while a similar backup on the grid can crash things.
