Finally, my purchase decisions are not affected by a few percent of inflation. I buy if I need or want something. Inflation is mostly an annoyance to me (saving is impossible in our current system).
You are contradicting yourself there. Because saving up in cash has been made impossible, as you say, you save less and buy more. The point is that people should save wealth in production, not in money.
Perhaps it seems that way but wealth can be stored in other means than cash. It does not neccessarily increase my consumption. Whether people 'save' in production should be a free choice to make, not a forced one.
