All of this is true. It doesn't mean that grid based solar and wind are bad.

Subsidies are examples of bad central planning at the hands of the government.

Look into volumetric pricing versus load based pricing. Load based is what you need to keep costs down in the long run. This is because load based pricing changes consumption patterns. Consumers hate it because they want a steady bill and they don't like to change their consumption patterns. Electricity billing has always been volumetric and people are resistant to change.

Volumetric pricing is an example of bad central planning at the hands of a monopoly. (A government mandated monopoly btw.) It means utilities need to match load to demand even when demand is sky high. That's really expensive in aggregate but the cost is socialized and nobody has to change consumption patterns or have inconsistent power bills, so it is the most popular choice. Tragedy of the commons.

Intermittent generation like wind and solar makes the problem worse. They get subsidized because they are popular with the public. Why does the voting public love all these terrible policies? Because the voting public is economically illiterate. They are, quite literally, a bunch of socialists.

Batteries solve the problems of pricing and intermittent generation by time shifting demand patterns. They also save a ton of money by reducing the need for transmission and distribution, the most wasteful part of our electrical grid.

Once you see the whole picture it's clear that batteries are the way forward.
