Everything you mention are actually political questions that can be settled by the final negotiations. I don't think we would necessarily give up any benefits or citizenship since the US recognizes dual citizenship. Land ownership in the US is not subject to citizenship requirement (ask the Chinese), so that is not a worry either. Living there as a non-citizen (depending how that goes) may be a little trickier though.
I have a whole different set of concerns I have been considering. Things like how to protect my family while I am fighting. After all, when the first shot gets fired, we become criminals and traitors until we win. The government will retaliate and harass our family members in an attempt to capture us. They would probably also bug their phones and closely surveil them to see if you contact them. When this starts, if I am in on it, I expect to say goodbye to my whole family for the duration. And since I don't expect to survive if we do not win, it might be my final goodbye.
Those are the types of consequences I am preparing for. I will be betting my life, my family, my fortune, and my sacred honor on it. I want everyone else who is considering it to think of those consequences and prepare for them also.
