If they are financially self sufficient enough to support their hobby while having their own place, transportation, job, food, etc, what on earth gives me or anyone else the right to set the measuring standard for what is 'too much'?

You are absolutely allowed to say "I don't like [thing]". You never have the right to say "[thing] is objectively bad because I don't like it". You can definitely say "I don't like when men spend X< amount of time or money on such and such". But that never gives you the authority to declare that it is actually a bad thing based on you not liking it.
