Yeah, if Starlink merely breaks even (and continues to grow), they will have pushed the commercial launch market potentially one or two orders of magnitude larger (in terms of mass) than it is today. It'll help pay for BFR, their Mars rocket.

Therefore, if Starlink suffers the same fate as Iridium (but without damaging the rest of SpaceX), that would actually be a big net win. Iridium emerged from bankruptcy, turned a profit and launched replacement satellites and is now in the process of a huge constellation refresh, using SpaceX's reusable rockets. If that happens with Starlink, that would be a complete success for creating launch demand.
