The density of downtown Austin has increased _substantially_ since 2015, but it's still not straightforward to live there without a car. Most of the shops downtown sell tourist tat, not useful items, and most of the everyday commercial districts are inaccessible by public transit.
Almost all new high rise construction just has a couple of floors of parking garage, and handles it well. I can't see buildings without that being commercially successful, especially since much of the work that attracts people who like downtown is out in the burbs (sometimes not even in the same county).

There is no parking ban being enacted. It is a removal of an arbitrary parking minimum. If they can't sell the properties without it why would they remove parking?
To point out that the intended effect of removing the minimums in Austin is highly unlikely to change actual behaviour in practice, other than perhaps in the units designated for low income people who likely will have to make do without parking.
