If you can't fix the problem you should not try to make it worse. Internet banking etc. are making things better. I do not know how bitcoin is supposed to make anything better for a non-criminal person.

That would be an irrational reason to hate cryptocurrencies, because they can be either inflationary or deflationary.
It's not about inflationary vs deflationary, but adjustable monetary supply based on need vs. predefined monetary supply.
