Now i would like a currency that looses some value over time to make wealth holders spend it on things that get profit and not sit on them. I Think currency shouldn't be a wealth storing medium.
Inflation benefits the people that have more wealth because it props up their assets, while it goes against the people that earn a wage (usually the middle class and the poor) because it devaluates their wages. The basic mistake you are making is believing the wealthy keep their wealth in currency. They dont.
Inlfation is not the only way to discourage storing wealth in currency. Maybe he just wants freicoin.
