Why is a rotary phase convert better than a 3-phase alternator driven
by a high-current single phase motor?

First reason is complexity. Second is efficiency, I'd imagine, though I'm
not an expert.

RPCs seem complex and prone to all sorts of vagaries (with SPC even
more so). Why not obtain high current 1 PH power, or several sources
of 1 PH power, and run a motor that runs a 3-phase alternator?

You think this is simpler than an RPC? I built an RPC from plans on the 'net
a few weeks ago, and it was a *lot* simpler than I'd thought. I wouldn't
want to bother with a generator setup unless I really had no other choice.
