I'm comparing writing a covered call to writing insurance, you are focusing on the incremental addition of a call to a long position.

Suggest that you cannot look at the writing of the call as an incremental thing - because the value of that call is very highly inversely correlated to the value of the stock upon which they are writing it (as a covered call). I.e. the stock has volatility x, the call has volatility >>x - but in aggregate their volatility is substantially less than x.

Amusingly/similarly, almost no one buys insurance without owning the underlying asset. The only exception I can think of is related to all the idiots that bought insurance on MBS that they didn't own (and didn't that turn out well?).

Compare writing covered call to writing insurance is not a good comparision. Selling put is a better comparision to writing insurance.
