Absolutely. We want FTL in stories because it allows us to tell a sequential narrative across vast galactic distances. We want FTL in science and mathematics because humans as a species don't like hard limits to what is allowed. We want FTL in our life because few people are willing to cut all ties to their family, friends, and society to wander off into the void without hope of ever returning or being heard from again. But... some people are okay with that finality of their decision to push limits and that's how islands over the horizon get discovered and settled.
