Further, when land taxes are passed down, they focus of physical goods and ignores IP and contract value. This means they are more flatly distributed throughout the population.
Third, many high return activities require almost no land. A stock trader or bank might make millions with the nanowatt of natural resources needed to flip a bit in a database. A plumber might need a lot of natural resources to fix your toilet
We already tax houses, and by comparison stocks are more liquid than a firehose and easier to value than a $2 bill. There is no excuse.
As I have grown my small business, I have come to an appreciation for how comically lopsided the tax code is to push all of the taxes out of the invest/return economy and into the work/consume economy. It's really quite something. Anything to avoid the right side of the Kuznets Curve!
