I don't think it's necessary to elaborate on how effective or how much a state subsidised university can fix the undersupply. The main thing is that it's easy to identify the undersupply in principle and see how that undersupply is a significant and not merely a trivial one.
Even if I accepted that you didn't have to elaborate on how effective state subsidised university is at fixing this supposed undersupply, you still haven't actually said how state subsidised university would even help here.
Besides, how would you even know it's a "significant and not merely a trivial one" without actually finding out how effective your remedy(state subsidised university) is? If it's effective at all...
But I do think it's necessary that you should prove there is a substantial benefit before you could even think about taxing people to provide it. For example, I think the police, courts and national defence are justifiable taxation expenses, but not state subsidised university via some vague stab in the dark at an unquantified benefit that you're yet to name a working example for. Your farmer example didn't make any sense, each individual farmer is still working to his own self interest by 'mechanising' (using the best form of production he knows) to get the most profit. If there is a benefit to society here, then an efficient farmer would see this and increase his production to profit from it.

I respect that view, but real advances in society are made by those who seek to expand the mind and not those who are merely 'doing their job'. These individual advances don't have to be great leaps forward, and can take place in any field. They are what takes society forward as a whole.
It's worth noting here that "Real Advances" can easily happen as a result of 'doing your job' or as a result of an investment decision. Ever heard of research and development? Ever heard of venture capital? Or what about the inventor just starting up a business with his own money?

Innovations also lead to more innovations. A scientific discovery, for example, can lead to more discoveries because the piece in the jigsaw reveals more of the big picture.
While this is true, it doesn't actually support your argument if you don't believe that there would be more benefit to us. Let's not forget you don't even think it's necessary to know how good the remedy is.
