Okay, assuming that gas giants granting unlimited resources through some kind of passive extraction process isn't going to happen any time soon, and the asteroid respawn bug currently being squashed leading to stripped systems, how about a compromise that also helps newbies on established servers?
Keep asteroids as being non-respawning, but limit it to claimed space. As in, as long as you have a claim on a system, nothing in it regenerates, as it is now. However, if you abandon a system, have it start to slowly regenerate. New asteroids spawning in, planets respawning, etc. If you wait long enough, a completely stripped system will revert to mint condition, as long as no one is in it.
This would encourage established players to move their systems out away from spawn as they age in order to move on to fresh new systems with full resources. If they abandon their mined out systems as they go, they start regenerating, meaning areas nearer to spawn would recover enough for new players to move in. That would mean that older players who have the resources to travel half way across the galaxy are the ones who have to do so to get back to spawn, while new players who can't do that are the ones who get to stay closer to spawn instead of making newbs fly across the galaxy on their first day just to get to unclaimed space to start setting up in.
