I think it is a psychological issue. If salaries get cut by 30% across the country, people go to the streets. If you devalue their currency, most people don't even realize it and just accept that the prices for certain imported goods went up.
But thanks to your example I see it has more subtleties: it is also a question who to take the money from. Making landlords poorer might be an easy sell to the majority of the population - if the population would have any idea of what is going on, which I doubt.
Services might just go away if they make less money.
Government declares that the arbitrary denominators of value now buy half the number of a different arbitrary denominators of value they did previously.
Because I am a locovore Luddite (for the sake of the argument), everything I buy is made in the country, with materials produced in the country.
How does the devaluation effect me?
