I'm sorry, I wasn't aware that you ever posed the question of why extinction is bad, so I didn't bother to answer it. And as someone who seems to be familiar with science/engineering, you should know that science is woefully inadequate to answer the "WHY" question, which is more philosophical/subjective in nature. Due to the nature of the question, I can't give you an answer that would not spiral off into a long series of further "Why" questions. So rephrasing that as a what or how question would be better. For example, "How does a decrease in biodiversity affect the well-being of humans?" And please don't ask, "How does a decrease in biodiversity affect the planet as a lump of rock floating in space" again, because I already agreed that yes, as a rock floating in space, the Earth is fine.
And yes, if we regressed to the state of Earth with no life at all, that would be very bad for people today. If you only care about the Earth as a solid rock and have no respect for the life that inhabits this planet, then there is nothing I could ever say to convince you that the impact of humans on the biosphere is detrimental. Whether biodiversity is "good" or not is obviously subjective, depending on whether or not you have an appreciation for life as we know it and consider this to be "good." Whether biodiversity is "beneficial" for current ecosystems and humans should be clear in that species are interdependent and removing one will affect others.
The fact that extinction events millions of years ago were larger than what we are currently facing has no bearing on what is happening here and now. And as a person living here and now, yes I am concerned that we are approaching a mass extinction rate. I don't live on a million-year timescale, so of course I would selfishly prefer to live with what we have now than with what we had millions of years ago. The moon, in and of itself, is not "bad." The moon is, however, "bad" for supporting life.
In summary:
Yes there have been higher extinction rates. The fact that we are driving the current rate to approach a mass extinction rate cannot be scientifically, objectively stated to be "bad" because "bad" and "good" are clearly subjective. Whether you feel that we are responsible for conserving and sustaining biodiversity is your own choice based on your own subjective feelings for the matter, but objectively, (1) humans are detrimentally impacting the current biodiversity; (2) this currently has detrimental ramifications for the current biosphere and the current human population.
If we are going to demand answers to the question of how extinction is "bad" (I prefer the term "detrimental"):
How is extinction bad for the Earth on a piece-of-space-rock, million-year time scale?
It isn't.
How is extinction bad for current ecosystems?
Species interdependency... connection of populations and abiotic/biotic factors on a regional and global scale
How is extinction bad for people?
Possibilities of finding new medicines, food supply
