Dude you are way off the truth here.

What do you achieve, by not seeing that the energy of the sun is limitless and free?

A burning planet.

Have you noticed it is burning?

Repeat, a burning planet, from extraction of capital, the energy beneath our feet, until there is nothing of value left.

Do you see plants witholding energy from all of nature until a ransom is paid?

So why is it OK for us to do it?

Plants grow up from seeds to spread their leaves to gather sunlight, converting that to supply all of life with energy. The growth of plants (The setup of their solar collection facilities) comes entirely from the energy of the sun, there is no cost associated with that.

We must plug into the sun to break capitalism once and for all, or we perish.

It is very simple.

If you prefer a more complex analysis including the maths, you can always have a look again at the Bitcoin as a Kardashev Hinge story.
