Plus you've got to deal with the biological offensive you're going to be exposing yourself to. Imagine a whole planet of microorganisms against which we have no immunity or medical experience. Do we even have an antibiotic that would be effective against the new lifeplans we'd encounter? The Spanish colonizers of the Americas died in droves, and likewise the indigenous population; all this from bacteria in lineages which our bodies were familiar with! Now imagine what you're going to experience on a fictional planet with an ecosystem that could support our bodies. We'd be living in hazmat suits for generations, or would have to burn the planet to ash and start fresh.
