The problem with this line of thinking is assumption that the OP would hold the stock until it reaches $200. But he wouldn't. He was ready to sell at $110. He is better off selling covered call + shares @$110, then only selling shares @$110. Another problem is the assumption that everybody can sell on the top (in this case, $200), while it's obvious they can't. And since when is profit of $10 per share == a huge loss…
And the problem with yoru line of thinking is that at the moment you write a call you are stating the time at which you may be selling the stock. if you didn't write the call you could sell at any time, but you did write the call so you set the time at which you sell. if the stock goes up alot then you end up losing alot of the upside.
If one sells a covered call but is not ready to sell the stock at that price, that's one's problem, not "covered call is a bad strategy" problem.
