I wrote earlier in the thread that Monica's indifference and dislike of sex is due to her internal psychological problem, a psychological complex (this is my theory) and the fact that she begins to enjoy sex under the strong influence of alcohol, when her nervous system relaxes, psychological blocks disappear, only confirms this. In the first stage of intoxication, one's level of mental comfort increases. When the intoxication is more severe, things get even worse and here we see the real Monica, who, as you correctly point out, forgets that she hates sex.
It seemed to me that Steve was already on board and had agreed to the investment a long time ago. But okay, even if he hasn't already given his consent, after what Monica did for him at the casting in ep3, I don't think there will be a problem with getting his consent. After all, she'll do it again).
For all of Monica's previous protests regarding her meetings with investors, it was usually resolved, as you may recall, quite simply. Biff promised her no money and to fire her from her job. The threat of dismissal and the possibility of becoming destitute is a universal argument that has worked for Monica before and will work now. The consequence of the dismissal is the inability to pay Victoria's money and, as a consequence, her likely arrest and sending her to the farm. Therefore, is anything else needed to make Monica even more desperate? I'm not sure about that.
