In the past, assets were never at risk of losing in outposts as you could not destroy them. POS, on the other hand, could be destroyed and assets looted from them. Structures are a combination of both and therefore asset safety is a logical thing to have as assets should not be at risk all the time when docked. Hence, I don’t think your idea has any merit and would most definitely not help to keep this war going in any way.
What should change is that structures should go away and we should return to outposts. They were so much better for content and reliability, and it was much easier with them to fight wars because you could just leave your assets in a place, go to another place and wage war there and eventually come back and reconquer your station to get access to your assets again. Structures, on the other hand, bind you in a place. You can’t just leave to another area to wage war there. You are confined to an area and if you want to go elsewhere, you either put your assets at risk or have to pack everything and rebuild later. Neither is in any way shape or form ideal for fostering conflict.
