I guess I don’t really understand the criticism, most of which seems to be “you should just build something that isn’t the thing you want to build.” There is plenty of aesthetic merit to the linear city idea on its own.
To use an example of a place that already exists: the city Łódź in Poland is situated along a single linear 4-5km street. Other neighborhoods branch off from it, but essentially the main road is the city’s layout. I really like it and think it’s a lot more interesting than it would be as a circle, even if the transit is theoretically not as optimal. There is something very aesthetically appealing about it.
