>Space-X can't make and launch Falcon boosters fast enough now.
The bottleneck is not Falcon 9 production, at this point it's largely on the payload side. A faster turnaround would certainly help, but there's only so much optimization that can be done.
The Falcon Heavy is not a priority because (1) much less demand from customers and (2) it's a transitional system between Falcon 9 and built-for-reuse BFR/MCT, so it will have limited use.
