Prove that 3.999... = 4

I think I could say 3.999 doesn't really exist. You will never find a number that has such a repeating decimal and terminates. (Of course!) So we really are infringing on infinity here, and the proofs that 1=2 because multiplying both sides by 0 is an identity.

Also, my example and yours are the same idea. If you put an infinite tower of blocks together, such that nothing is between them, could you say that the top block is the same as the one below it?
