So you believe you understand the motives of other players better than they do themselves. Therefore nothing they can say is likely to make any difference to what you think.
Oh, I'm listening, but so far everything that has been said has just confirmed it.

You have yet to explain what prevents players accomplishing the same thing with fixed ASIs. Particularly salient because for years we have seen players doing exactly that.
The same player that absolutely want a 16 have been doing it for years indeed by choosing only the class/race combination that provided it. On the other hands, players who don't care about this have been exploring the other 90% of the game with full creativity since the beginning without having any problem.
So if the floating ASIs now allow that first type of players to explore combinations that they did not explore before because that 16 was the one thing preventing them, all power to them, I have never said that it's a bad option, I've only said that it's a power option because the only thing important that "leashed" their "creativity" was not having a 16...
At our table we use a low point value random generation, drawing from a deck and assigned as drawn. We use several rules options that consciously power-down our characters. And yet we prefer floating ASIs. The dissonance with your views couldn't be clearer.
Maybe it's just that you hate being double frustrated.

It's just that I would have to see what that "low point value" brings to be sure what it gives you.
Players may care for motivations that you are unwilling to accept they can have. From your point of view, it is indeed inexplicable.
We've been here 29 pages and I don't know how many on the other thread, and yet someone (not even me) on the other thread just said : "Have we seen an answer given yet that did not involve getting a +3 modifier in the primary stat of the PC's class?"
I'm perfectly willing to accept any answer, but the only ones that I've had are along that line, with subtle variations...
