In many cases, your mass issue compounds, a heavier craft means it needs bigger thrusters, more fuel......

It's only true if you send stuff to the Mars or Jupiter. To send 1kg to LEO you need about $4'000-$5'000 and to send 1kg to GEO you need $25'000-$30'000.
That's if you use cheap "obsolete" Atlas, Dnepr, Proton, or similar modern replacements. Futuristic Space Shuttle was, indeed, 5-10 times more expensive, but that's not a problem anymore.
At these prices easily achievable savings make sense, but if you need one fully engineer to work a year to save measly 1kg once then obviously it makes no sense at all.
