The main predictions and suggestions mentioned in the article is a good starting point. I’m not sure what endeavor is the best for human labor but digging and filling the same ditch is not it. You would be hard pressed to convince me that anyone making such suggestions should be taken seriously. Much of our “money isn’t real” monetary policy is thanks to this thinking.
There are alternatives that don’t require you to believe in silly things like the example above. Check out Thomas Sowell: Basic Economics.

You aren't supposed to take Keynesian gold digging as a serious economic policy. It is a commentary about how your actions can be constrained so much that doing anything logical or reasonable becomes impossible because it hurts some special interest group.

No, that started after the death of Keynesian economics. You know, the era of "monetary policy can fix anything"-Friedman. Monetary policy is inefficient so you have to do a lot of it and you can never stop.
If you want to take Keynes seriously, you should read a liquidity theory oriented book.
And yet it is still better than doing nothing. The problem is that nobody has introduced a self stabilising market economy so far. No matter what anyone tells you. Capitalism doesn't work without some government intervention.
I want to introduce a self stabilising type of liquidity but I am not ready yet to start a company. I am planning on doing something in two years.
