Unfortunately, when you get into situations with more than 150% difference in
pixel densities between displays (as we've been creeping towards in the last
decade) that's the only way to display text the user will be able to read.

You can check it now easily, just get a run-of-the-mill full-hd 15" laptop
(not even a tiny netbook), a run-of-the-mill 22" or more screen (nothing
especially uncommon either), create an extended desktop with both screens and
try to set a satisfying font size. I defy you to find a setting that won't
look way too small or way too big on one of the screens. And it won't matter
if the user likes small or big fonts.
