True, however divisibility is not the limitation being talked about here. In short rate of change of requirements for space by Maid owners with 100% of the supply will guarantee below-potential growth rates for the network vs an alternative more widely distributed SNT policy. Divisibility does not play a role or make a difference as it is not about how many SNT there are, rather how they are to be distributed.
I have referenced here previously “general economic theory” is not generally accepted and there is a wide, deep and ever growing economist movement to change economics from the inside employing tools from various branches of modern science to do so.
It would be better if you could show that you have an understanding that linear econometric models have failed in almost every capacity to be predictive in the real world complex systems we call economies. Feel free to read up on the economists that have embraced techniques developed in the scientific realm for the study of complex systems (referenced here previously) and are having much greater success at modelling future states of complex economic systems for doing so vs linear econs.
However all this is way off-topic and I have no desire to wade into those weeds with you. You will have a much more productive debate and learning experience engaging with the “rethink economics” or related branch groups, as referenced.
