Correct. Adding tail emissions to Bitcoin without unanimous mutual agreement would be debasement, but not inflation, as we have defined the terms. Tail emissions vs the increase in lost coins would likely eventually get to the point where they were about equal, and this would keep the practical quantity stable, and would only be inflationary if the demand for money actually lowered, generally if the productivity of the world lowered. Without tail emissions, Bitcoin would remain deflationary even with slight slumps in productivity so long as people keep losing coins and not recovering them, or keep burning them.
