They can only charge what the market will bear after all.
When what you’re selling is a limited resource necessary for survival, “what the market will bear” easily becomes “all the money you make”. Otherwise you end up homeless and won’t be making any money.
What do you think “passive” means in the term “passive income”? I don’t care if it becomes harder to earn “passive income”, especially if it’s coming from people just doing what is necessary to survive.
