You are assuming that this doesn't change the size and certainly that's how the normal notion of size works. But the question is whether we can create any order relationship on the sets with the desired properties.

The properties he mentioned defines a partial order and partial orders can be extended to total orders (given axiom of choice). So it is in fact possible.

Counter point. This is always inevitably a thing. They were only making the implicit explicit.

It's a Bible reference. Jesus supposedly said that "A prophet is honored everywhere except in his own hometown and among his own family". When you grew up with someone everything will be colored by your past experience with them. You remember all the grandiose stupid things they said in the past. If they are saying actually wise things now you will not believe them as much as you should. On the other hand if they are still saying stupid things other people have not yet learned caution.

There is something to technical analysis. But you do need to approach it rationally rather than by performing magical rituals.

The markets are made of a finite and sometimes very small number of participants that may have their own reasons for buying and selling unrelated to company performance. Figuring out what they will do is the basis.

Maybe Bob is looking to sell a lot to free up cash for private jet. Maybe Alice buys every month the same day like clockwork as she gets her paycheck. Maybe Charlie thinks the stock can't go about $50 and will take profits at $49. Maybe Debbie regrets not buying and is likely to fomo buy soon.

Probably can't figure this out one by one, but can in aggregate.
