"Simple concept" is subjective. I'd bet that discussing "simple concepts" with an engineer or scientist would likely cause your mind to grasp and instinctively try to relate to your own memorization of facts. But that shouldn't preclude you from discussing what you do know, or for that matter, sharing it with the world.
This is wrong. The fact there are more than sufficient resources to care for every citizen does not preclude the need to pay for something.
Suppose that I self-sacrificed by under consuming and taking a risk. Instead of enjoying my free time and spending my money, I choose to spend many days building bricks. After a while, in a hut-less society, someone might ask why they need to pay for my bricks, when there are more than enough to build huts for everyone.
Raw materials may be abundant and "free", but labor, investment, and capital are not. They're they product of blood, sweat, and tears. Hardly free.
