Personally I like parquet floors, though I prefer carpet in the bedroom, tile in places like conservatories, and lino in the bathrooms. I still put some rugs on the wood floors, though.
but....
What's your alternative? Most if not all are colder than carpet, some by a lot. And a lot of people like the patterns on carpets. Carpets can keep noise down, not just of feet, but all noise- hard floors reflect noise, carpets absorb it. UK housing is often poorly sound insulated. Wool carpets on hessian backing are fairly benign for the environment, and good for farming as they provide a market for wool- renewable, like the hessian.
So the alternatives then. Bare boards? (in most modern houses that means bare MDF- not very healthy stuff anyway, and if you varnish that it looks terrible, and even in many older ones with actual wood boards the boards would need a lot of work in terms of filling and replcing boards ( not easy due to tongues) to make it possible to have a non-draughty, non-splintery floor).
Laminate? Not hard wearing, not renewable, lots of nasty glues in it. Difficult to access under it for maintenance of pipes and wiring. Would probably need replacing sooner than carpet. Easily chipped and knocked.
Engineered board? More expensive than laminate, a little more possible to refinish when it wears, but not many times, probably needs replacing nearly as often as carpet.
Parquet? Wonderful stuff, but costs a lot of money. And there can be issues because of the use of hardwoods- there certainly would be if everyone had it.
Concrete? Very cold. I worked in concrete-floored places for years, in the winter it sucks all the heat and energy out of you via you feet unless you wear clogs or heavy boots, and it can be damp. And it is ugly. Yes we do get hot spells here, but we get far more months of cold and damp weather.
Tiles? expensive, easily cracked, and, like concrete, unforgiving for falls of humans, including the elderly and very young, and and drops of objects.
Lino or other plastic coated floorings? Also cold and sticky on the feet, but some are at least cheap. All made using the nasty chemicals you mention.
