The only alternative I see is that you're proposing bitcoin's price should generally rise faster than inflation when inflation is positive.

Is that really what you mean, and what you think my parent comment meant? Inflation is a mechanical thing; to get that effect, you'd need a financial instrument that was specifically defined to produce it.

He meant that the price of BTC expressed in USD should be going up with inflation.

It is. If you want people to understand that you have some other meaning than that, you're going to need to phrase it better.
