There have been a few misunderstandings here.
Val, no-one here is telling you not to do this, but to do lots of research, especially in terms of legislation/planning laws etc. Think things through clearly and then proceed on an informed basis, don't follow a kneejerk impulse which many of us have seen before many times. In addition look carefully at location - your intended site is quite remote so may have limited appeal. And I don't know if you've done much camping in Wales, but it can be a dire experience at times, Wales isn't so verdant for no reason

and although Toby Wrench and others have finally got planning permission, I'm guessing it's unlikely you'd be allowed to erect any more permanent dwellings, especially on rented land.
Places like Brithdir Mawr have been many years evolving and have nearly fallen flat on their faces several times in addition to the years of stress and worry re planning regs. And, in response to one of your later comments, I would rather pull my fingernails out than live in a hippy commune, but that's just me. Many here would love the opportunity, I'm sure.
As for diet, I think there has been a general misconception that you are vegan. My reading of it is that you are vegan by diet only, not ethically. So I'm guessing you still wear wool and leather just don't eat animal-derived products. However, your comments about vegans and your lack of understanding as to why they don't eat honey and object to having sheep and chickens is another example or your lack of knowledge or interest in alternative lifestyles.
For me, this, even more than your ill-thought out land-share scheme, is why I for one would not be interested in your proposed plans. Jumping on the Self-sufficiency bandwagon seems to me to be another of your money-making, solopreneur ideas (Google is a truly wonderful thing). I'm guessing there's not much money in fashion, book searches or dietary info at the moment.
I wish you well.
