It’s odd that you would end by assuming that other sports don’t suffer from the same problem. If you buy crappy shoes and run in them for extended periods you will hurt your feet and knees. If you try to bike harder than commuting on a cheap bike you’ll hurt yourself when the brake pads come loose. No idea about skiing but someone in this thread said they felt a noticeable difference, I’m not sure if it translates into safety though.
The beginner equipment is more likely to get you hurt by breaking, and the bearings will be very very slow.
For other sports, running/biking/skiing/etc I think this difference is not as pronounced.
