No, it's not just lost faith. It's about as true as saying somebody that can't run a mile under 5 mins or bench press 300+ pounds just "lost their faith in running and bench pressing" and that's the only reason ever. Some things are just hard for some people. Or impossible. Some of them can be improved with training and practice, but not instantly and with a lot of effort. Some will forever take much more effort than for other people and leave one exhausted. Some may be just plain impossible. Some may be possible, but people may decide, rightly or wrongly, that they are so hard that the effort is just not worth it.
