Thanks for the informed commentary.

Ha! I hate to post this as it is a simplistic analogy, but there is a counter intuitive answer to this. In that it probably wouldn't add that much to move it back. The first time I ran across this puzzle it blew my mind. And had to do the math to convince myself.

However, in reality moving back a bit would add more length than the string girdling the earth problem would suggest as there remains extra distance for items that run up to the barrier.
