One thing your initial reasoning left out is that human concepts are not simple, either. Money may seem simple until you start to consider currencies, rounding, taxes, fees, etc. Text may seem simple until you consider punctuation, different alphabets, math symbols, emoji, and other special symbols, glyphs, or characters. Names may seem simple until you consider suffixes, names that consist of multiple words, middle names, cultures that place the family name first, nicknames, name changes, various accents and other "special" characters (that probably are perfectly normal to the person with the name), etc. As a programmer you often have to deal with other programmers' solutions to handle all this complexity, which may be flawed or simply different.

I mention all this not to pick holes in your logic but because it sounded like you were trying to look more closely at your intuition.
