Tumble driers are for the most part pointless, since one only need hang
clothes up for them to dry, the driers waste money to buy, space to
keep them, and cost to run - none of which there is any need for.

You clearly have no children. The sheer quantity of laundry required would
require every surface in the house to be used for drying clothes, which is
ugly and impractical. We often do four washes in one day.

It would also require twice as much bedding (and storage for such), as you
couldn't turn it around in a day.
