The effect of inflation eroding your funds can be eliminated by investing it effectively thought. Serious savers should be earning returns well in excess of 2%; my regular bank account pays more than inflation. Similarly competent lenders would have priced in margin on top of a 2% inflation expectation, so they'd be making a slightly smaller profit on their loan portfolios rather than a loss.

That's not the case when a governments freezes withdrawal of certain assets whilst proposing to give them a 6% haircut.
