when you learn physics (e.g. Newtonian mechanics) you idealize concepts like "frictionless" because it teaches you valid concepts that you can carry forward, and you don't soil your diapers at every step of learning. Do the same with economics if you want to actually learn it, don't think "what's wrong with this", think "what's right with it, what can I learn from it?" Look at history, what economics explains is what happened.
you can't learn classical mechanics from a few paragraphs, but that's how long an HN comment needs to be. I will promise you this, if you reject what I wrote and remember most of the doomer dreck here, you will not learn economics at all.
The problem with Newtonian mechanics, especially idealized frictionless versions, is that it gives you a wrong impression of how the world works. Much better to understand and accept friction, because it leaves you with an accurate understanding, instead of an easy-to-learn version supported by fundamentally flawed concepts.
Within physics, there are much, much, much better models than Newtonian mechanics for conceptualizing economics.
they never ever teach physics the way you describe, they teach it the way I describe, and they never stop at the frictionless assumption. I am intellectually advantaged over you in every possible way, yet you do have a comparative advantage; unfortunately it's at spewing tendentious argumentative not-even-interesting nonsense.
