If they add a penalty for votekick then all you'll see on the forums are people raging about how leaving a dungeon needs a longer penalty because they have nothing else to do besides make angry forum threads while waiting for a replacement healer to queue IP for AV. Blame Square for making such dungeons with totally bogus design flaws or the general playerbase for being so terrible at this game that most people don't even want to give groups who start those instances with them a chance.

SE will never be able to punish "meanies" enough for you to feel justified in your impotent nerd rage, nor would they ever punish those players enough where they will actually bother to modify their behavior. It's not like the game makes you sit in a corner for that 30-minute lockout and think about what you did. Either boot them or vote abandon when the option comes up.

...I feel like this thread is more about wanting to hold tanks and healers hostage more than anything. All a DPS has to do is blink wrong and they're given the axe. If vote kicks were really so precious like the forums want me to believe, why does the window pop up almost instantly anytime a DPS's connection takes a sneeze? (Had this happen in a Library run the other day; I, BRD, voted no, but the WAR and the WHM voted yes. SHOCKING, I KNOW. The other DPS had been gone no longer than 30 seconds.)
