Its not that big of a deal in the end. If someone were to figure out some top-secret function in your program, with disassembled code they probably sat at a desk for weeks on end with a pad and pen, trying to make sense of it. Most of the disassembled stuff I've seen, has been along the lines of:
Code:
mov [ebx+0012041241],[eax+123142343434234]
It'd melt your brain trying to determine what is even in those offsets.
