I have to not agree with most of your suggestions with how i feels the game needs now.
I agree Hot air balloons do need improvement or removal.
You can build twig and ladders on other peoples land because when this was not possible before - you could build bases on tall rocks and you were impossible to raid.
Lockers can be bought at bandit camp for 40 scrap as soon smack a few barrels and if you dont have a level 2 workbench in the first 3 hours of Rust, you need more practice.
Electrical, horses, aircraft are all in a good spot right now and pointless monuments are good for people who like to build in remote areas since they are pretty much dead zones for pvp action.
