The grid needs to balance input and output. You can't just "throw away" power.
It's a real problem
not the "electric companies are losing money" part, but the "we need to keep the grid balanced" part.
That can indeed be a problem.
It is however not what the MIT guys wrote as being the problem: they quite literally said the problem with too much solar generation at peak times is that it drives prices down.
Also, curiously, the prices being driven down actually helps with the real technical problem that you point out: those consumers who can move their consumption times will tend to move them to those hours when the prices are lowest thus helping solve it. Same thing goes for investors: the more the price is pushed down at peak solar production times, the more appealing it is to invest in things like storage or even solutions with lower efficiency (such as green hydrogen or electricity transportation cables to markets less well served by solar).
The low prices aren't the problem from a technical point of view, quite the contrary: they're an incentive to invest in solutions (which is going to employ a lot of techies, so supposedly MIT would be all in favor of it)
