Most of VFX's problem isn't technology. If you read the post, its not really mentioned.
No the main problem is indecision.
As other people have pointed out, virtual sets require a solid and stable vision of what the story and look of the movie is going to be, before filming starts.
Some film makers work like this. For example medium to high budget TV shows between 2010-2018 (before marvel basically.) Notably also chris noland.
There are numerous examples of poor planning/indecision: the two poorer modern james bonds (quantum and spectre) both started shooting before the script was fixed. So loads had to be made up in editing.
Another example is this:https://www.youtube.com/watch?v=yfVu52tZxd0 "the sand room" from prince of persia. This was designed, scripted and executed by one of the VFX houses, because the producers realised that they had no way to link the two halves of the film.
In Clash of the titans (2010) they spent loads of money making mount olympus with a real set. Hired all the old masters. after filming, the producers were like "Nah, I don't like that, lets make it like google maps". So the set was removed (I'm not sure if it was digitally done or a reshoot).
Then Hades's cloak was a pain because the producers first wanted smoke. Then ink, then smokey ink.
As alluded to in the post, the producers can get away with this because the contract is to do as many revisions until its done. There is little to no cost hit to the producers of the film to fiddle, be indecisive or back track.
