Like everything, it's a matter of trade-offs. Spending a moment
thinking about what you're doing before you do it might cut your RAM
usage by 20% without materially increasing your programmer time cost.
But coding everything in C "for efficiency" is almost certainly a bad
trade, for the reason quoted.

There can be special boundaries in resource consumption. Fitting
something inside an Amazon Micro instance might be important for you,
in which case you get just 613 MB of RAM (a weird figure, I know). Or
maybe you need to stay within 8GB so you can allocate the other 8GB to
the database. Or whatever it is. But any time it's flexible (where you
basically just pay twice as much to get twice as much), it's usually
worth going as far as you can.
