I wouldn't say money is a coping mechanism, because many men do want wealth for other reasons than getting laid. Actually the majority of wealthy people are like that. some just enjoy the whole "game" of making money. I truly sympathise with those for obvious reasons :)
Well as mentioning in the OP, money can communicate power - which is attractive to women. So maybe this is a way that makes Trump a bit more attractive. But I will not deny that Bill Clinton and JFK have higher sexual market value than Trump.
