I know guy, working a route for days, and finally doing a 5.13. After, they send it with the use of cam. Big deal. Go in a gym, try parallel bar, train a routine many time...and you will be able to do complex move. This is the same as climbing a 5.13 after many repetition. It could be fun, you could like it. But I don't like it. I prefer to learn like jackson 20 years ago when sport doesn't exist. And I am pretty sure that you don't learn by yourself, but with old climber with a strong trad ethic.
If you define trad climbing as some one who place cam in a crack...you are right that many people trad climb. In that way...the only think you can do is climbing classic with a lot of pro.
If you define trad as the people use to do it when they use piton and have to place less gear to avoid to be to tired, and you learn the similitude between hamp rope and dynamic rope and you use that technique, do multi pitch route in remote area, etc.. you never qualify 80 percent of the climber using cam as trad climber.
ordinarly, a good 5.10 climber can doa 5.8X route without too difficulty. There is always sand bag or situation that are very dangerous. Taking the decision to not playing the game of people who just plug cam in the rock versus challenging some one to place his life in danger just for there plaisir...I prefer to keep my definition of trad climbing.
