That they may be inevitable does not support the argument that they
are necessary. By the way, how can you know that the junk (and
biological contamination) we left on the Moon will not cause some
problems at some time in the future? At the very least, the
contamination will not be spread by wind. Such is not the case on a
planet with an atmosphere, like Mars. Again, you have the foresight
of a grave robber.

ok.. so your argument for not having manned missions is because of the
bacteria that we may carry to another world, which may or may not have any
real effect on that planet.

Probes carry bacteria too, based on your reasoning, we shouldn't be doing
those either.
