No we don't need 2n=2n+1 to be true, but it's possible to name each odd number with an even number. And when the total number increases to infinity, things will go against human intuition, and that's what a subdivision in math called "analysis" deals with.
And okamiyu, guess what, I can name every rational number with a natural number!
