The problem with this way of thinking is pretty much the same as with a central planner. You just assume that we notice every damage we’re doing fast enough and that we can push through the necessary legislation fast enough and without loopholes… It’s just the same game of whack-a-mole that you mentioned.
I agree that in our current capitalist and parliamentary-democratic system that might be the best solution we have… But it’s still a shitty solution overall.


Expanding on that: in competitive electricity markets, in theory, total demand is met by the cheapest plants (by “marginal price”: how much does an additional unit of electricity cost?) that are available.
The marginal price of PV, wind and hydropower is pretty much zero.
The next cheapest are usually older nuclear fission plants and coal power plants.
Then is a huge gap and then come newer nuclear plants and gas fired power plants.
But all of these plants aren’t built over night. So maybe before all of the datacenters, total demand may have mostly been met by renewables and coal and gas power plants only operated a few hundred hours per year. Now, total demand rises and those plants need to operate more often. That’s why the prices rise just because of demand increase. Other effects (e.g. changes in regulation, corporate greed, …) might be at play as well.
