"As for the monospony, you can get that with an oligospony as well. They conspire to milk the consumers dry and only then fight for what's left, and you end up with cartel behavior."
That's monopoly or oligopoly you're talking about there, control of supply. What Marx was (rightly) much more worried about was monopsony, a single buyer. In this case, a monopoly purchaser of labour, who would then be able to determine wages.
Delightfully, the only place this has ever happened was in Soviet states and boy, was Marx right, labour got screwed big time.
"Well, unregulated, capitalism WILL" which is why even classical liberals like me are just fine with regulatory action to break up monopolies.
