given that abiogenesis occurred very rapidly on Earth, that is weak evidence that abiogenesis isn't hard in an absolute sense.

We don't even know that it occurred on earth at all. It might have occurred elsewhere in our galaxy and traveled to earth via asteroids.

most Universes in which life exists will have life exist in more than one place.

Why? I don't see any reason why that should be the case. If you take for example posts that internet forum users write most of the time most users who write posts only write one post.

That would make it more likely that there's life on other planets, not less likely.

Most planets and stars in the universe are not in our galaxy. If our galaxy has a bit of unicellular life because some very rare event happened and is the only galaxy with life, that fits to a universe where we are the only intelligent species.
