Your small nuclear reactor is going to need almost as much engineering , plumbing, safety mechanism, personnel, maintenance, etc... as your big nuclear reactor.
Siting of an SMR is somewhat different (albeit related) to the SMR concept itself. You might cluster them together (like the plans for 3 RR SMR at Wylfa and 3 at Ringhals in Sweden).

Sure, that is economics, not thermodynamics. I don't necessarily agree with the SMR manifesto, but it is conceivable that improved financing, construction, operation and oversight could make an SMR cheaper than a larger reactor.
