But the key thing is you can't have a locked diff on a normal road
car, as it would ruin the tyres and make the car undrivable on curves.
Off-road vehicles can usually lock the centre diff and possibly the
rear diff, but that's a conscious decision taken when driving
off-road, not a default setting. So if a car unexpectedly hits a
slippy patch, even cars with lockable diffs will be unprepared. But
ASC is ready and waiting to spring into action at all times.

There is always the option of a limited-slip diff. But that's way more
complicated, which is what makes ASC a better option - every modern car
already has the hardware, it's just software.

Yes, LSDs are now confined to just a few high performance cars, as ASC is
so much cheaper and easier. The electronics can also deliver different
characteristics for use in different conditions, without changing the
hardware.
