If someone asks you to work 14 hour days but you only choose to work 8 hours a day, are you artificially limiting the supply of your labour? Or making a sensible choice for yourself? The monks have decided they don't want to turn the drink they make into a massive corporation that would be required to make it at the volume the world wants to consume. That is to be applauded - not many people have the strength and sensibility to say no when the demands of the world are greater than what is good for them and their community.
The article tried to paint the monks in a favorable light for limiting their production for environmental reasons but the phrasing rings hollow to me. They didn’t stop all production, or release the recipe to the world. They merely limited their output which, much like many companies with monopoly power are currently finding, allows them to have a higher price per unit, while no one can come in and compete in their market.
Their attitude is akin to how people complain and demand stuff from open source projects and why authors are annoyed when supporting such projects.
It reminds me of "The Menu" movie, the producers got fed up with the consumers and they took drastic actions. Wasn't a big fan of the movie but I can see how creators would go to such extremes or at least fantasize about them.
Do you work every hour you possibly could? Would it be reasonable for someone to complain that you owe them more work because they would really like it if you worked more?
It’s a drink produced by one monastic order from (presumably) locally harvested herbs. There most certainly is a natural limit on how much can be sustainably produced before it no longer is the same drink.[1]
They chose to maximise availability over time (and work/pray balance) rather than maximise short term availability.
[1] Where that limit is is of course up for debate, though.
