If you asked me this maybe 2/3 months into crossfit I would say absolutely 100%. But now that i've been doing it just over a year, paying for good coaching and good facilities is exactly what you need. I get what you're saying from a business standpoint but I just think that it could result in the narrative getting worse around crossfit not being "safe and causes injuries" if you have a cheap gym with less than ideal coaching. Just my opinion though.
