Diego has a valid question. There's nothing wrong with being motivated by profit. I certainly am. Being only motivated by profit is questionable, but is that really the point of the original question?
Due to the amount of discussion generated, it's clear that this question is on a lot of folks minds whether they be of the money is bad camp or the money is good camp. I did find a few examples of folks that have the appearance of being profitable in these responses, but I certainly did have to dig for them.
I will give you an example of a yes answer to this question.
One of my friends is profitable using permaculture techniques. He doesn't realize it's permaculture, may not have heard the term, and didn't sign up for the religion. He is, however, engaged in a completely natural farming system that synergizes on the connecting of different systems together. He doesn't use chemicals, he doesn't till, and he co-exists and harvests from the natural forest system around him. A lot of his income is derived from foraging choice edibles that local restaurants pay big money for. He spends a lot of his time nudging the forest to provide for him, what he is looking for. He also generates income from free range chickens, that feed themselves, by selling to a wholesaler.
Every year he makes more money than the last. I didn't ask him how much, because that would be rude. My observations are that things are going well, though. Anyone who pays folks to lug around giant rocks to certain areas because he thinks they're cool has to have a bit of financial slack. Did I mention that he's happy and isn't stressed out at all? I know for a fact that he is profitable.
Myself, I see this as a freedom, fun, and survival thing. I make a very good living selling technology to large customers, but I have absolutely zero faith in our financial system. I'd rather buy a fruit tree than put the money in a 401K. I do both, because it makes good financial sense to hedge bets by playing different games. I don't feel bad about trying to make as much as I can as fast as I can make it. It doesn't consume my life, I rather enjoy it.
Large concentrations of wealth have the power to move mountains. Sure, we can make giant swales on huge properties with shovels, but that takes a lot of time. Building eco-systems is all about time. If you can compress the effort in the beginning, systems can get off the ground a lot faster. Can you rent an earth mover without money? Stop being so judgmental about money and the desire to be profitable. It's OK. It's what we do with the money that matters. If you can't stand the money that you have because it's so terrible, get rid of it by signing some paychecks for folks that need it.
If you have lofty goals of feeding good food to good people while saving the environment, I would encourage you to make as much money as you possibly can and put it all back into your intentions. Money is a resource, just like water, sunlight, and organic material. Don't get worked up about it. it's just a spell on a piece of paper. If you understand what it is, and it's place in the world around you, it has no power over you and will do your bidding.
Don't get me wrong. I highly respect folks that reject money. One of my friends lives in the woods, making his living by foraging what he needs. He doesn't need money. I aspire to have that type of freedom.
We're all entitled to our own views as to what motivates us and how we make our way in this world. I would love to see this thread continue with some answers to the original question. I would like to find more examples of successful permaculture based businesses, so I can learn from them. The video about the dude that converted a traditional orchard into a permaculture system, was rather inspiring, for instance. The other video with the seed company fella with the amazing water works, was fascinating.
It's OK to think money is bad. It's OK to this that money is good. Let's not get lost in trivial things and get excited about awesomeness instead of being offended that certain folks might not completely share our world view. There's so much grooviness to agree on.
