For most cases, you're correct. However, some specific fragile
ecosystems do not tolerate introduction of new species and human
meddling (the extinct megafauna of the Americas is an illustration
of the latter).
Also, we haven't yet seen the end of the experiment. In absence
of dramatic breakthroughs (autopoietic molecular systems) what we're
doing now is not very sustainable, not just through our numbers.
Our current primitive technology gives us leverage do do more damage/
human unit, and this trend is getting worse as such tools spread
further. So we need to make a series of concerted breakthroughs, soon,
and this is our challenge.

You're channelling Tainter's The Collapse of Complex Socities, but Diamond
gives plenty of examples where Tainter was empirically very wrong. Have you
read "Collapse"? If you haven't, you should.
