Exactly. The extreme case is the boolean type, which could easily be 
represented by a two-value enum. Or, if you were feeling masochistic, a 
FK to a separate table. Which is easier?

People regularly do stuff like having domains over finite text values, 
or having a FK to a separate (static) table, or using some sort of EAV. 
Enums are type-safe, easily ordered, relatively efficient and don't 
leave zillions of little static tables all over the place, a combination 
of attributes that none of the alternative solutions in this space present.
