You keep ignoring what I'm saying, which is those unique attributes are reflected in a population through racial traits.You don't have to care.
The example was to illustrate a point.
Even in a large randomized population, the racial modifiers would bear out to a statistical truth.
Yes, you are absolutely free to care about your PC, and nothing else.
That PC which is a member of a species.
That species, with unique attributes reflected in a population.
Which while you don't care about, others do.
"+2 Strength" is not a unique attribute. In fact, nine races and three subraces get +2 Strength (bugbear, centaur, dragonborn, dwarf (mountain), gith (githyanki), goliath, half-orc, locathah, minotaur, orc, shifter (longtooth), tortle). And that's not including newer races with floating ASIs or Tasha's variants. But only a single race has the traits Natural Athlete, Stone's Endurance, Powerful Build, and Mountain Born: the goliath. And every single goliath will have that unique combination of traits regardless of what their Strength score is or where they put their ASIs.
Giving goliaths a +2 Strength does not make them more unique. It just discourages many people from using goliaths for non-Strength-based martial builds and prevents people from creating goliaths who are innately gifted in other stats.
