Those are really vague questions, but I'd say yes. Certainly someone brewing at capacity would be selling it all, and usually someone selling it all would expand to at least their current capacity.
If you look at the BA stats, 1.8% of craft breweries closed in 2011, and again in 2012. That number has been dropping for as far back as I can find the data (2007: 5.2%).
Edit: Official Poobah of No Life?! I thought it was more of an ad hoc position.
