Take the scenario where there was a directed panspermia mission towards europa that containing a range of organisms up to the complexity, a simple fish and a range of species to make a self sustaining ecosystem that have been picked to be adapted to the enviroment they are going to and they successfully colonise . Would have to consider probabilities of where great filter is. If great filter is before this level of complexity then panspernia would be good, if think that on balance the whole space of possible civilisations are on net positive. However in a case that the great filter is after this for example from great ape level intelligence to humans requires very specific evolutionary incentives, and it is unlikely to get past. Then could have a very high chance of something similar in value to the ‘wild’ animal population and a low probability of human level civilisation. If place the value of human level of civilisations as many orders of magnitude better than the (possible) negative welfare then the argument could go through, as being positive EV even if placed lowed probability of going from small fish ecosystem to human level civilisation.
Based on NASA’s extensive planetary protection efforts to prevent interplanetary contamination of the explored worlds, I think it is plausible now. https://en.m.wikipedia.org/wiki/Planetary_protection
