The 72 PPI number was used back in the days when typical resolution was like 640/800/1024 horizontal pixels and display less than 20 inch diagonal. It was the Golden Age of pixel art.
Apple had been experimenting with the idea of Resolution Independence during the transition to “high resolution” LCD displays (1280/1440/1680/1920 horizontal pixels) before giving up to integer 2x (and later 3x on iPhone to overcome deficiency of OLED sub pixels) scaling on what they now call Retina displays. This was the rapid transit to 100~110PPI for non-retina and 220 PPI for retina on desktop and over 300PPI on mobile.
Modern Mac can also do non-integer scaling (eg 1.2x 1.5x) well enough on retina displays if you need extra working area. For example all current Apple Silicon MacBook Air default to non-integer scaling on its internal screen.
