If this seems hyperbolic, then I would like to know where the line is drawn. Repeatedly spending a large input for small transactions opens you up to theft, doesn't it? If all you carry are hundred-dollar bills in places where meals cost a few, then what would you do before flashing your entire wallet every time you want to spend money?

If you're going to obfuscate your coin inputs in some manner and not simply use the original inputs for the transaction, then what lies in the middle ground between such a procedure and mixing services?
