The reason that brass ONE-PIECE flatbuttons do not date after the 1840s is that the invention of button-making machinery which could INEXPENSIVELY mass-produce "fancy" 2-piece buttons made the plain old 1-piece buttons fall out of favor with the public. Kinda like what happened when color TVs became price-competitive with black-&-white ones.
That being said... you are quite correct that some "needy" people kept on using the old 1-piece buttons from the early-1800s, even into the civil war era. Clothing wears out and gets thrown away, but the brass 1-piece buttons didn't wear out... so low-income people would salvage the buttons and use them on new-made clothes, for decade after decade.
On that subject... we civil war relic diggers frequently find early-1800s brass 1-piece flatbuttons at Confederate camps way out in the woods, far from any house-site. When the Confederate supply-department was unable to provide the correct replacements for lost Military buttons, needy CS soldiers substituted whatever was available to them... including wood buttons, bone-buttons, civilian flower-buttons, and "obsolete" plain ol' flatbuttons.
