Why assume that mirror life will somehow have a magical advantage over normal life and take over the world? If being opposite is what makes it exceptionally dangerous, then normal life would also be very dangerous to mirror life. The entire biosphere would be hostile to mirror life. Whatever mirror organism you synthesize probably already has countless natural predators and biological processes that interfere with every stage of its lifecycle.

this is true until you look at different trophic levels. Single-celled mirror life bacteria would be deadly to larger creatures.

The planet is teeming with non-mirror things at every trophic level.

The mirror bacteria has to somehow perfectly dodge all of the countless non-mirror things that can kill it (even unintentionally, like a byproduct molecule that just happens to blow it up or get in the way of reproduction), but somehow still be able to execute its own mirror-biomechanism to kill non-mirror things. And every step of the kill mechanism would also have to perfectly dodge non-mirror things interrupting it.

Not that it can't be done in theory, but it would be easier to just make a normal superbacteria, or maybe even nanobots.

How? They would have never been introduced to such mirror organisms, except potentially (but not certainly) around the formation of life 4 billion years ago.
