The traditional yoga culture of India is indeed odd to us in the modern world. Your opinion is however based on a concocted sentimental mental speculation and has no philosophical grounding or authoritative backing. Nevertheless you are entitled to your opinion.
You are correct about humility though. It is the primary quality of a yogi. Traditionally very advanced self-realized souls were known to live from begging, and still do, but being vegetarian they would never eat food cooked by a non-vegetarian for example. That is what the yoga texts recommend, otherwise your consciousness is dragged down. You may not understand this because it is too subtle for your educational level on yoga. Some advanced yogis simply dig in the leftover food rubbish, and live off scraps like that, being very detached, but subtler concepts like the consciousness affecting the food are scriptural or Vedic Sanskrit brahminical standards, not mundane sentimental western speculations. Having trained under yogis in India, I learned this from them so I'm simply repeating what I heard. Your opinion shows that you are somewhat aware but not trained in the subtle science of yoga or self-realization.
