Don't even think about it. And tell them exactly why. The team will not survive the stresses of early startup life with this decision put off. It's going to be a hard discussion even now, just imagine how bad this will be with revenue coming in the door, pressure to grow, some members of the team really stepping up and others not working out.
You have a BA in economics and have worked for some fairly large companies, and, like me, you're a company founder. Tell me, is this ever a discussion that is "easy"? And, is this discussion ever "settled"? Seems to me, it's settled exactly until they (a) get funding or (b) hire a CEO, at which point all bets are off anyhow.
