Something that doesn't seem reasonable about that view is that players can choose race to give 16 just as much as they might place a floating ASI to do so. Seeing as I've observed many players doing so in their race choice, I do not see fixed ASIs as a solution to your concern.It relates based on the fact that some people are absolutely fine with any character concept and a character with a 14 or 15, whereas people wanting the FLoating ASIs are mostly doing this to obtain a16. So if someone tells me that he just wants to have the floating ASIs for a "character concept", I'm wondering what type of "character concept".
How are fixed ASIs a sure solution to your worry that players will ensure they have a 16? Do you just disallow 16s at your table?
