I think the inflation people have a trouble with is fiat fractional reserve lending.
Why?
Because if you fractionally lend money, that original money that was lent should in theory be distinguished from debt by having some essence. The issue is with fiat the original money and the debt become indistinguishable when they monetize the debt by printing money.
If you lend based on gold, that original loan is still owed to you, so by default every loan that was fractionally created from gold is still the very same original gold. Therefore the money is distinguished from the debt because it must be returned to the lender since you cannot counterfeit it (print).
The same applies with bitcoin fractional lending as does with gold. Pre-programmed inflation in bitcoin should behave nothing like fiat inflation, because the debt cannot be monetized. The debt must be returned to the lender.
And if you notice throughout history gold has inflated and will continue to inflate, but since gold mining requires energy, as bitcoin mining does, the inflation is beneficial to its value because it allows for a larger adoption base and solves the first adopter problem.
Inflation is not the enemy of bitcoin.
