ELI5: why is milk available in skim, 1%, 2%, and whole but not any other fat percentage like 5% or 10%?

Whole milk is about 3.3% so to get higher percentages you have to remove water, and surprise surprise they do this already: 


Half and Half:10.5% - 18%

Whipping Cream: 30% - 36%

Heavy Cream: 36%

Butter: 80%
