1) If you get the cheapest price online, then you shouldn't worry about price discrimination

Non-sequetor. Unless you mean "the cheapest price anyone paid" as opposed to "the cheapest price offered to you."

Price discrimination often isn't price discrimination at all....Price discrimination by definition is two identical products offered at different prices

Except price discrimination does not have to be between two fully identical products. It's a silly No True Scotsman argument.

standardized pricing is a relatively new phenomenon as far as global history is concerned

So is not dying of smallpox. Standardized pricing is not as big an advancement, but it definitely is an advancement.

If you live(d) in a bartering society merchants would absolutely sell you the same thing at different prices different times of the day

Have you ever lived in such a society? Or is this your idealized free market assumptions?

And using computers to automate the entire system allows that system to happen so fast and frequently that it totally changes the nature of the interaction. Consider the difference between assigning a cop to patrol an area and look for crimes (/. approved) and putting up the ring of London to spy on everyone (/. creepy).

Sorry, there was some bad typing there. Consider children of single mothers on welfare - there are two groups, one whose mothers are forced to work, others who are not. Studies show that the children in the group with mothers who are forced to work are (a) more likely to end up on welfare and (b) more likely to go to jail. What these imply is that any benefit of "seeing a work ethic" is outweighed by the lack of a parental influence. Certainly, these studies suggest we should not force welfare moms to work.

There may be some changes, once kids are in school.

then you easily come to the conclusion that something must be preventing people from building housing

Your Econ 101 answer ignores a lot of things. For instance, houses are not interchangable. So, building 2 houses is frequently less profitable than one bigger one. In fact, complexes where I live are being replaced by smaller, more expensive ones. You also ignore that there is a limiting factor in land. Capitalism works great for shoes, because you can produce as many as you want. Housing faces a much quicker falloff in marginal benefits (as you leave urban areas). Further, the "they" was intentional. Unless you have a large plot of land, you cannot replace it with more smaller apartments. So, either a high rise, or a few acres or something. But, that becomes prohibitive to collect, because those are already owned by people. So, there really tends to be oligopoplies of real estate groups that can afford to build new housing in areas.

Housing also is one of the areas with huge externalities, so obviously there needs to be regulation.

don't let facts get in the way of a good story, but even if their mothers don't work, the average number of jobs per adult in areas with lots of welfare moms is more than 1. That is, they are poor because they have non-well paying skills, not a lack of work ethic.

But, more importantly, as I said: studies show that children of welfare kids do worse with regards to "not going to jail or themselves ending up on welfare". So, whether you think seeing such a "work ethic" is important, it clearly is empirically worse for the child. As, you know, being less likely to go to jail or end up on welfare seems to be ending the "cycle of squalor", which happens when mothers mother.

If you're wondering why I put "work ethic" in quotes, it's because I think parenting well is a job. Not one well recognized monetarily, but certainly a job.
