If you look at pro wrestling as a business and nothing more, then sure. If you look at pro wrestling as an art (which it is), there's a lot more to it than financial profits.
If you look at other forms of art like music and film as just businesses then Nickelback and Michael Bay were two of the best artists of the 00's.
It's an interesting debate as to whether or not pro-wrestling is an art form.
I'll present the counter argument. Pro-wrestling's origins were purely commercial. The way it came about is when real wrestlers, "shooters," figured out that they could have more entertaining matches if they "worked" in front of the crowd, and therefore they could attract a larger crowd and make more money. Sometimes, the wrestlers would have the "shoot" match backstage to determine the outcome, and then put on a worked match with more crowd pleasing "spots." Eventually, when promoters got involved, they figured they could make more money still by "booking" crowd pleasing results.
In other words, the entire reason pro-wrestling exists is to generate the largest crowds, and therefore the most revenue possible.
So, today, if there is an "art" of pro-wrestling, it is surely related to this raison d'etre.
Pro-wrestling is to actual wrestling as the Ice-Capades are to figure skating; an explicitly and intentionally commercialized derivative.
Or to use your analogy, pro-wrestling is to actual wrestling as the genre of "arena rock" is to music. Now, you can say Nickelback sucks, but you'd have a hard time arguing that they weren't one of the best arena rock bands of the 00's simply because they were one of the
biggest bands of the genre, and the whole POINT of the genre is to attract large crowds to large shows.
In other words, we all want to be big rock stars...
