People cant want a lot of things that aren't economically feasible.

Toy example: if everyone demands at least $30/pound for some risky kind of coal mining, because it's such a pain to do and they'd rather a) rest or b) do easier work at any lower price ... that doesn't mean coal miners are colluding or that coal mining is a monopoly.

In that case, if you want a $29/pound alternative, your desire is economically unrealistic.

If there's a single coal miner that does it for $29/pound -- and is thus the most efficient one -- that miner will dominate the (tiny, niche) market. But it would not rightly be called a "monopoly", but "a single provider who is legitimately better and would lose business if he started to falter".

Telling me that someone currently dominates a market does not prove monopoly power.
