Here's the secret to a post scarcity society. You can't get one by providing unlimited resources to everyone. No society has unlimited resources, not even the Culture and especially not the Federation. The Federation wouldn't be looking for new energy sources if it had unlimited resources.
No, the secret to a post-scarcity society is to successfully indoctrinate your population so they'll never want more than society can (or should) provide them. They can have all that they want, if you manage what it is that they want. Realistically there's no reason why anyone wouldn't want to have their own personal FTL vessel...if only to escape when their planet is about to be destroyed, an eventuality that I must point is totally routine on Star Trek.
But they have managed people's expectations so they don't ask for more than they can get. The people who want to do the kinds of things you imagine are simply identified and treated for their mental illness until they have more reasonable and socially responsible desires. Tada! Post-scarcity achieved!
Cyberian is a time traveller from a rather dystopian possible future where cyborg androids are created with animal features to distinguish them from humans. After the war he was made to fight in, he went into business as a bounty hunter and it was in that role that he ended up pursuing his prey into modern times, where he still works as a mercenary/bounty hunter. He's inhumanly strong, quick and has enhanced senses and still has his bike, weapons and armour from the future.
