If such a model is to be protected from the dynamics of a free market economy (Higher demand driving prices higher) it requires significant government intervention, at the very least, analogous to the metro system in certain cities, to ensure that the different strata of society have access to it without breaking their backs. However, as with most non-essential consumables, the model is susceptible to privatisation whose motivation is often, solely the maximisation of profit. Perhaps a lobbying group analogous to the NRA could help counter such overtures for privatisation by the industry.
