3. Push with a finger - now your just making things up.

The reason i say it needs more practice is because, its omni-directional. While it probably doesn't require as much practice as a swerve drive it still has the complexity of one. A 6wd yes does need a lot of practice to make perfect but it is very easy for a new driver to control. I personaly have never driven a mecanum robot so my expirence comes from swerve drives.

Yes they don't need chains or sprockets, but they are still larger and very heavy. The larger diameter the wheel, the more force you need to excelerate regardless. Add weight and the required force goes up even further.

Yes maybe claiming that someone could push a mecanum with a finger was a exaggerated. Frankly I might just be spoiled by robots that can't be pushed at all.
