You are clearly knowledgeable about the things you’re talking and made a conscious decision. It seems like we agree that there is some risk, but you consider it insignificant while I it’s quite substantial. Only time will tell whose right.
Monero’s inflation is not a percentage, but rather a fixed 0.6XMR per block. This mean as the supply grows, the inflation percentage will slowly go down, so there’s no exponential losses like with fiat inflation. Currently the 0.6XMR/block work out to 0.9% of the mcap, in the year 2100 it will be down to 0.5%: moneroj.net/tail_emission/ (<- great site btw, it has a few BTC diagrams as well). The tail emission was chosen so that it works out to be less inflation then gold, but high enough to have a decent security budget.
