First off, Rheinland players in this thread, you're all way too personally invested in this. If your personal feelings drive this, it won't be fun for anyone. Separating you from your character is important both for fun and good rp.
Otherwise:
Rheinlands mercantile economy: can't believe you missed this! Those who forget history etc. H-Fuel! Rheinland can't cut everyone off without forgoing space travel. And running that inefficient kruger station isn't going to solve it. Not enough product by a long shot, and government subsidies won't mean squat in a closed economy.
LWB: saying this as an LWB since 2009, they will never accept anything like this, both for inrp and oorp reasons. The LWB exist because of Rheinland's shotsighted dumbness, they'd be pretty wary of another dose.
Also those ALG donations...haven't seen those for a while. They get hit the same as anyone atm afaik.
Also the LWB is like what, 500 people?:D
Fyi most insurance companies irl work at extremely low profit margins. You won't be better off without it, trust me.
Material resources: rheinland's bled dry, no? Enjoy the unsustainable fuel expenses of militarizing 7 and 11.
Tl;dr please don't play this as something that rheinland 'must' win, it will suck for everyone. Be objective, rational, realistic, and no powerplay (some rhienland govt guys would totally take bribes, this is life)
