Noone seems to be considering the fact that regardless of how long the Catalyst has existed for, how could it have seen the destruction of all galactic life enough times to make a far-reaching judgment since if that occurred there wouldn't be organic life existing in Mass Effect?
In addition, there are other viable possibilities to what will happen to galactic civilization. Perhaps organics and synthetics will merge voluntarily long before the critical point - in fact, Geth uploading themselves to Quarian suits is already a primitive form of this.
Finally, the comparison between Geth and Quarian advancement is inherently flawed. The Quarian's have been exiled and have been riding around in ancient, retro-fitted ships as Tali tells you in ME1 - they also have to essentially "scavenge" for resources. The Geth, on the other-hand, have a planet and are able to plough resources anywhere they want in the Veil - think of it like playing C&C where you have all of the Tiberium fields! Lastly, the Geth that the Quarians are prominently at war with are the heretics, that are only as advanced as they are due to Reaper intervention.
The issue with the Catalyst, and the reason Shepard should be able to dispute and argue with its assertions, is that it thinks just like a machine. For example, it doesn't see the difference between the Synthesis ending and life in the galaxy obtaining this state themselves, since it views it as an equation where the end product is the same. However, for us, for organic life, it's vitally different.
It is also essentially looking at things from a deathless perspective whereas organics naturally have to accept death. By attempting to control everything, what it offers is a state of existence like limbo: no death but with no freedom it's not being truly alive either. By leaving the galaxy to its own devices, there is a serious risk that all galactic life will be destroyed, but this is a metaphor to life: Life has serious risk, and life will end some day, but to be alive one must accept death.
So if BioWare want their ending to be all philosophical, rebelling against the Catalyst can still very much factor into that: we choose life with all its risks rather than immortal limbo!
