I don't understand why being so negative about 'modern gyms'? Everybody decides for themselves. As a personal trainer I see 90% of 'crossfitters' (functional training) who don't know how to make a proper squat or deadlift and they are doing functional. There is always the most injuries from crossfit, because people jump into functional training without supervison. For this kind of people would be better that they would first use machines and than free weights.

I agree that free weights, proper snatches and jerks are the best for you and you should do them on daily basis...but, first learn how to properly execute them. 'Modern' people have no patience and they want everything now or even yesterday🙈😀
