Floating ASI isn't about min-max at all. If you wanted the most powerful character possible without floating ASI, you could, it just limited your choices. Floating ASI is roleplay improvement because it frees you to play the race you wanted to RP without sacrificing functionality.
This is exactly a min/max argument. 100%
You do not want to RP, at the expense of being as effective as possible.
Its LITERALLY, about the mechanical benefit, aka minmax.
