This is a sports car, the whole point of having close ratios is so you have more choices for the optimal gear, and you have to put work into shifting to make that happen. Tell me why you need lots of passing power in 6th gear when your 5th gear can do it much better? Fuel efficiency doesn't matter in a sports car? Tell me, would you rather be cruising at 50mpg, engine very quiet, or 32mpg, engine roaring? Fuel efficiency is a byproduct of proper, intelligent design.

And no, a short gear going 70 vs long gear going 80 is a massive difference in load. A long gear going 80 could be putting the engine at 90% peak efficiency while the short gear could be putting the engine at as low as 50% peak efficiency on some cars, while the actual power requirement difference between 70 and 80 is something like 40%.
