As I noted there are other important things for wizards that don't rely on intelligence score. If majority of your spell casts are not DC based halfling wizard is better than high-elf or human.
Factually, it is still a handicap compared to being someone with +1.
Overcoming constraints (in this case slightly lower main score) for sake of doing what you want (playing a halfling wizard) requires finding creative solutions (such as spell choice adjustment, gear consideration, party composition) to make a constraint less impactful or in some cases beneficial.
Nope, that's pure nonsense. We're not talking about a finely crafted story written by an author who puts in careful limitations to powers so that characters are forced to overcome them creatively. Outcomes are based on the random roll of a die. There is no "creatively" getting your way around sheer random chance.
That leads me back to my question, why do you want ASI if rolling for stats will be possible? And if they would add free edit (which I'm not against) you could make your stats, as if ASI was in place.
Rolling for stats - especially when playing in a party which is all otherwise point-buy, like the Origin characters - can lead and encourage players towards rolling a character which is more overpowered than a point-buy character. Are you EVER going to answer MY question?
You have put forth no sensible reason why someone else choosing to put in a +2/+1 where they want - when nothing stops you from leaving them at the default - personally damages your fun. You haven't answered that because you have no argument, and are just going in circles. I see little reason to continue.
For some people, if the option to be overpowered exists, they cannot allow themselves to take anything less. I, for example, actually really like high charisma or intelligence Barbarians, which is sub-optimal because Wisdom then falls off and I have a weak saving throw, so I am sort of hurting myself there, and when I tell people at my tables that's what I want to play and end up with a 14 in Charisma they give me a weird side eye like having the overpowered option of picking Variant Human and having 17 str 16 con 14 dex and 14 wis was possible and picking either GWM or Resilliant: Wisdom was possible, so why am I a Tiefling who can't cast spells while raging, dropping wisdom, and picking up a stat that's never used in combat? Well, because it's fun, but some people can't bring themselves to do that. I just want to play as Gorge, the Half Orc negotiator who is definitely capable of handling it if the negotiations go south, instead of Gorge, the half orc in the back that stays there until things to bad. He fight good and that all he do, that's boring.
I guess what I'm saying is it can remove the fun for some people because they will only ever create a character that has the best stats for their role and blame the possibility of min-maxing on their actual min-maxing, which isn't how it works at all, if you think min-maxing removes creativity, just... don't do it? But not everyone thinks like that. If they can, they will feel compelled to. That's why maybe when you click New Game you can just opt in, since mods will add it anyway this functionally makes it an Opt In anyway, even though it being on by default is also opt in since when you change race the game can just automatically select the default ASI... The character Elebhra is describing still exists, which is ironic because they are also saying they wouldn't do it if they could do something better, but a dexterous wizard can still be a fun thematic choice especially if they impliment GFB or other such cantrips so their weapon damage with daggers does scale up, you'd just be opting into it as opposed to being forced into it, and like I said, some people cannot bring themselves to opt into weaker choices for the sake of thematics, roleplay, or fun.
Of note, floating ability scores also opens more roleplay options like a nerdy Barbarian or such builds without being human, since you may just want a +1 to 3 stats. I would be choosing to remove optimization in favor of roleplaying options.
