Novelty sets like these are deeply unpleasant for regular chess players, because they interfere with normal pattern recognition. There's a huge difference between being able to tell the pieces apart and being able to read the board at a glance. It's like reading a book in bad handwriting instead of clear type - you can decode it with enough effort, but you can't read fluently or scan the text.

I think the parent commenter did read that and their concern is that tournament chess has a touch-move rule (if you touch a piece you have to move it).

This set is certainly a cool art piece, but not particularly functional if a player has trouble distinguishing pieces visually.

The queen looks like a slightly larger version of the bishop (or is that the knight?), I could see someone confusing them if they're sitting at different levels.
