Your only problem with Windows appears to be that it named the scaling setting "DPI" until Windows 7 or so to handle scaling. But as the parent mentioned, Windows is definitely superior to MacOS, as it provides arbitrary scaling ratios, and renders text perfectly at any ratio.

To go deeper into nitpicking, DPI is not even that misleading, if you take "inch" in DPI to be equal to 72 points as used in font sizes. Then a 72pt font on the screen with DPI X will be rendered with height of X pixels.
