As the old saying dictates Mars certainly isn't a free lunch. However, I wouldn't necessarily agree that we have solutions to the problems I mentioned. I'd agree that we have some potential solutions most of which are in very early stages and often quite expensive. Both issues have kept wider adoption from occurring.

Vegetarian diets are neither a new thing nor wildly expensive. They're old as dirt and can be far more economical than heavily meat-based diets. People don't want to adopt them just because they prefer the diets they have now.
