Rubbish. Town planning is based on research. Unlike your estate agent marketing slogans borrowed from daytime TV. Research is a learning process and responds to problems.
Town Planning was also liberty from the tyranny of the land owner. You and others talk of life style choices as if you are doing online shopping and expect to pick and chose from every possible configuration possible from an infinitely sized warehouse somewhere in China. Confusing consumer choice with freedom like 1950s America.
Town planning originally had to respond to the realities of industrialisation and anarchy because the macro-problems were growing exponentially. "Town planning" is now concerned with a myriad more interwoven issues such as environmental pressures eg those caused by the very suburb that you worship, responding to urban regeneration and the economic models that drive it as well as well as numerous social issues that appear to spring from how we structure and legislate the physical world (a bit more anarchy please Westminster council).
This feeling of control and dictate that some seem to be sensitive to all ultimately came about from public action not some middle aged geek overlord with a cardboard masterplan. Although Abercrombie was close (I say half jokingly, to be fair he was responding to the issues of the day with all the knowledge they had, we would all be better off if he got his idea to electrify and bury all railways coming into London to fruition, yet his road building plan was highly disruptive and ultimately led to public backlash some decades later). As ever it is the execution that sometimes falters through lack of foresight and ultimately poor understanding. Again this comes back to research.
Put up a photo of an ugly post war estate that was built after a slum clearance programme 60 years ago and so what? We have learnt the lessons and moved on. To argue otherwise is simply ignorant hysterics. You talk of enjoying living in a village near a town with all the mod cons and yet do not admit to the expense of such a set up and the hidden subsidies involved. I'm sure the ex-villagers from 100 years ago who fled the poverty there are stunned by your amazing foresight.
This discussion illustrates what is often wrong in town planning. Too many individuals with a particular vision or agenda.
What good planning provides is a mix of housing choices for every requirement. Chafford Hundreds is not to my taste, but I do know people who love living there. And given the cost they are certainly not forced to do so.
I like being in a village near a town and having a garden with patio doors open in the summer, even if there is rubbish among the child's toys. Others prefer dockside apartments with a balcony.
