For what reason? Ohm's law says it makes no difference aside from
losing
a little in heat to the transformer. Is there something I'm missing
here?

If you have too much resistance, you won't be able to dissipate the required
amount of heat at a given voltage. (Likewise, if you used too little, you
may have to run it off 120V - at an excess of current.) If you put in too
much wire, it may well be that the ultimate temperature will be too low at
240V! However, a stepup transformer will put more voltage on it = more
current = more power.
