Supply and demand. The demand is extremely high, with every high school graduate being pressured to "go to college!" (to what end, few know) and student loans being so easy to get. The supply is limited, as a nation can only produce so many professors and places for them to teach.
Your suggestion "US fed govt should just pay for every ones college education" (however paid for) would just increase the demand even more. You'd still be depriving a large number of intelligent and brilliant people from ever getting a college education in USA by the sheer mass of bodies signing up - and you'd still have a limited supply of teachers & facilities, so odds of the "deserving" getting what they need remains low.
Demand outstripping supply, prices naturally rise until equilibrium. Making payment easier thru cheap debt or government handouts doesn't solve the problem because that increases the demand without improving supply. MOOCs, by improving the teacher/student ratio by orders of magnitude, does work toward solving the problem (and decreases costs as well!).
