[MCU] Why doesn't the average person learn to be a sorcerer?

After the events of Endgame I'm sure people would know about Dr. Strange and all the sorcerers that fought against Thanos. We never saw Dr. Strange pay to learn magic so what's stopping anyone/everyone from going to one of the sanctuaries and learning magic? I feel like in real life there would be portals everywhere.

It's basically the same reason why the average person doesn't learn to be a neurosurgeon. It's REALLY hard, requires tons of training and practice, and most people who try end up failing at it and finding something else to do instead.
