Reality is that the bank just indexes your loan with inflation, so you have to pay more.
Inflation is just a hidden tax on everyone - and people should protest against it. Great way of the rich (who are heavily invested in assets, not cash) and government (who gets cash inflows from the central bank - and central bank makes money by printing money) to screw the poor.
Also if we look back price stability under the gold standard is a myth. Prices might have been broadly similar in 1800 and 1900 but there were some massive ups and downs in between that lasted decades. Predictable and stable inflation seems like a much smaller issue
It obviously does on the macro level.
On the individual level perhaps not so much. Unless you have a lot of debt as quite a few people tend to do. Then it also has obvious benefits.
Pre inflation standard bond yields were around 4-5%. Combine that with longterm deflation over several decades (e.g. late 1800s) and then consider how severely screwed you are if you have a mortgage on your farm..
