My reference to 18-9 etc is perhaps somewhat misleading and I do understand the financial etc aspects mentioned by Adrian above.
My point is really about the size of the plot of land that a golf course needs in modern society, worldwide society, the priorities of modern society and its effects on golf - land usage, population, water, time constraints, maintenance, clubhouse size and the like.
And of course with a rolled-back ball a smaller area of land effectively plays bigger.
