It is customary and polite to quote the post you are responding to rather than make people read the whole thread and guess. But hey, I guess manners are not your forte.
The premise is faulty. The government loses no money as the USPS is self-financing. I do not know how that affects Rand Rover’s position but you can see why it is necesary to know what you are responding to. It seems to me more defending privatization than disappearance, but, never mind.
Again, privatization is not elimination. If you quote the post we know what you are responding to and we have the necessary context.
No, as very clearly stated in the OP,
At the present time there is no talk and no chance of it disappearing. You need not worry.
