Launching isn't the whole mission though, even if you can achieve that rate. For every launch you also need hours of time for rendezvous, docking, and fuel transfer. And even if somehow there is a solution to this schedule, you're talking about doing it 10,000 times safely and without a hitch.
Indeed, the parent comment was making a bad assumption. If you look at it that way, refueling can happen anytime in the 2-years between windows. So say 10,000 launches over 730 days is 13 or 14 launches per day. Given multiple launch sites, seems feasible enough (in the same sense of feasible as producing 100,000 tonnes of goods destined for mars every 2 years).
