Of course it would, but the allies in 1941 were officially UK and Russia and primarily concerned with defence. Nice to think about flying to Hamburg and Paris but you will meet Bf109s
I think the point is if you had (good) fighters with that kind of range you wouldn't have to stay on the defensive. You could raid their airfields before they took off. You could escort your bombers to Hamburg and start bombing them back. You could bomb their fleet and pre-empt any invasion activity. If you were the Russians you could destroy their supply lines long before they even get to Stalingrad.
If you have ever been in a fist fight - defense and counter punching is fine but it helps a lot if you can put some pressure back on your opponent at the same time.
Of course you also have to have enough fighters and pilots to go on the offensive and England and Russia probably didn't in 1941.
