Never, never, never believe any war will be smooth and easy, or that anyone who embarks on the strange voyage can measure the tides and hurricanes he will encounter. The statesman who yields to war fever must realise that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events. Antiquated War Offices, weak, incompetent, or arrogant Commanders, untrustworthy allies, hostile neutrals, malignant Fortune, ugly surprises, awful miscalculations — all take their seats at the Council Board on the morrow of a declaration of war. Always remember, however sure you are that you could easily win, that there would not be a war if the other man did not think he also had a chance.
You raise an economic, political and maybe societal, ehr, question? It is not entirely clear to me what your inquiry or proposal is. You can help the community accepting your topic by being more clear and information rich.

The money printing is not really a danger in that sense. Yes, I also do think we should manage to have a better banking and currency system, FIAT is less than optimal, but it's not the case that it doesn't work at all either.
I don't know who you are referring to with "normal people", but I am inclined to not see the HN crowd as normal people. Depends on your parameters of course.
