Yes, I've read about Mark Shepard with a lot of interest. However that's just one farm. It's yet to be seen if his methods will work elsewhere, if his claims for productivity can be substantiated, if his productivity can be duplicated, and so on. In short his work is, currently, at best a prototype.
If you're going to claim that regenerative can be as productive as conventional then you need to point to systems that are widely used and whose productivity figures are reliably gathered.
> "Modern" societies employ between 0.5 and 3% of their workforce in agriculture [1]. If we'd tripple the share of agricultural workforce but in return drastically reduce the energy use and make farming a net carbon sink instead of a substantial contributor to global warming, I think it would be very much "practical". As things stand, we could pull the required labour simply from people doing tele-marketing and nothing of value would be lost ;-)
You miss the point. It's not about the availability of labour. It's about the price of labour. It's more economically efficient to reduce labour as much as possible. I'm not claiming this is a good thing. It's the reality of farming in a free-market society.
Mark Shepard's system has been reproduced/used as inspiration in many other places, I could name at least a few here in Germany from the top of my head, all of them commercially successful (tough I admittedly do not have calorie production figures for those and am not sure if they exist). But I'm not sure why the example of his farm warrants so much skepticism. He isn't in a special location, on the contrary: his soils were a corn farm previously, degraded and according to the generally accepted advice at the time unusable for Walnuts, one of his main crops. He didn't use any special technology, etc.

But farming is not a free-market enterprise in "modern" societies. It is the most subsidized and among the most regulated among all enterprises in industrialized economies. German farmers derive half their income and all their profits from government (mostly EU) subsidies. I don't know the figures for the US, but I'd bet that they are similar. Farming, by who and how farming is practiced is basically entirely defined by political priorities, which at this time are mostly still based on the technological and scientific developments of the 1930s-1970s, which have created some very well established commercial interest groups (chem-ag concerns, farmers unions, etc.).

Because if it was that good, I'd expect to have been seeing all kind of articles about the massive revolution in agriculture. If there wasn't some kind of catch, why isn't it seeing wider adoption?
As far as what counts as "commercial success." It'd really have to be something that can compete with commodity agriculture to be a solution. If it's a "commercial success" because it's some boutique thing that can charge 10x commodity prices to make up for 5x costs by selling to self-consciously "ethical consumers" and elites by marketing its good local green permaculture vibes, then I don't think it will be anything but niche producers.
