For the record. So much of what you have stated above is so inaccurate that it makes it pointless to try and argue with you.
Example: You suggest that it would be easier to collect the debris than to deflect it into a decaying orbit. Do a little research and you will find that the 8000 or so tracked objects represent a total mass of approximately 3000 tonnes. Where you gonna put it? Some pieces are 20 metres in length.
Example: You suggest that it is "easy to dodge space debris". The 8000 tracked items represent only those pieces > 10cm. They are but the tip of the iceberg. There are estimated to be upward of 100,000 (maybe as high as 500,000) pieces 10cm<debris>1 mm. A "spec of paint" was enough to punch a pretty substantial hole in the "bullet proof" window of the space shuttle. How do you dodge something you have no idea is coming? (Not to mention that "station keeping fuel" is one of the major limitations upon the lifetime of a satallite.
For example. One of the major roles of the 1.3 billion Euro ATV, is to use it's thrusters to regularly push the ISS higher to compensate for its otherwise rapidly decaying orbit (Remember that discussion? So big objects don't decay due to atmospheric drag huh!)
I looked to refuting your blanket dismissal of the feasibility of the ideas I expressed above. It turns out that the math underlying Orbital Mechanics is far less onerous than I had thought--once you find the right source of practically, rather than theoretically expressed information. What eventually stopped me was the requirement to be an "approved registered user"(*) in order to obtain the basic data (TLEs) with which to construct a simulation. Well that, and the distinct impression that it wouldn't sway you one iota.
Al-Qaeda might nip up there and start throwing them at the US?
There are reasons why using a redundant space shuttle wouldn't be a good idea. None that you broached though. It's mostly to do with its mass. Regularly changing the orbit of so massive a structure, most of which would be redundant for the task, it too costly. However, that doesn't mean that it would make sense to use a to-be-retired-shuttle to put such a project into orbit.
And the Molinya orbit wasn't such a red-herring after all. For two reasons.
