Therefore the government should pay for all of it. In the USA, since 1970, funding for science has declined. If we could merely get funding back to the trend line of 1930 to 1970, then the government would certainly be able to cover this kind of research. More so, it is completely incoherent for anyone to argue "We should leave this to the private sector because the private sector is more efficient than the government, but this process is wasteful and so we must grant a monopoly to whoever is willing to do this." Rather, as soon as someone says "We must grant a monopoly" they are also saying "the private sector market place has failed" and therefore they are also implicitly saying "The government should do this."
