My friend finally said you don't understand. I don't care what you have to do to get crème brûlée, and I will pay for it.
The waiter said I understand, and shortly came back with crème brûlée. He had ordered it from another restaurant and hired a taxi to go get it.
The waiter got a nice tip, and my friend's date enjoyed crème brûlée for dessert. Everyone was happy.
And that's how "shortages" work in the free market.
All the anecdotes about going down the street for homely puddings, have little to do with the larger markets in the modern world.
There are no shortages in free markets.
Perhaps your point is that, on a free market, the supply and demand will always meet at the right price point. Yes, that works long-term. Short-term, it doesn't, because sellers have every reason to look at the first and second derivative of the price - to hold off selling until they believe the demand for a product is about to reach its peak - and only then actually sell out their supply. This of course will cause the prices to go down, but by that time, the emergency may just be over, and a lot of people who needed the product then will have suffered and/or died.
The way I see it, this is literally the same mechanism stock trading is based on, and yet nobody here seems to have a problem understanding it there. Supply and demand, right? So if I know the demand tomorrow will be larger than today, I'll hold off selling my stocks, and I'll hold them until the point I see demand starting to fall back down.
Of course it does.
> hold off selling until they believe the demand for a product is about to reach its peak
Of course, people famously are unable to correctly predict when that peak is, and so your scenario will never happen. (Some will sell early, some late.)
If you're good at predicting stock prices better than everyone else who is trying to, you can make a billion in short order. Good luck!
Because farmers can easily breed beef and chicken; fishermen cannot easily breed their own fish - the fish have a nasty habit of not respecting imaginary property lines in water, and you can't just put fences in an ocean.
It's worth noting that the free market is precisely why fish are threatened with extinction. It's a textbook tragedy of the commons, for which the solution is regulatory in nature.
Fish farms are a real (and growing) thing.
For example, why don't we have shortages of beef and chicken, while fish are threatened with extinction?
For another, during the California and Yukon gold rushes, men rushed to the gold fields. Women rushed, too, but not to mine the earth for gold, but to mine the men for their gold.
