If you're going to quit because you lost a ship, you're not the sort of player to make it into a Super-Cap fleet for a big coalition. We're talking about people who do things like month-long marathon spawn camps or week-long fleets of shooting at towers. Everybody with a Titan in this fight has at least one other character they play most of the time.
Also I think you dramatically over-estimate the impact of this loss. All sides have dozens of other systems and income and funding that are relatively safe. PL/N3 lost a key forward base and a weapons cache, but it's not a crushing territory loss, and they still have one of the largest super-cap fleets in the game - they may have been set back weeks but they've been in this war for 3 months already and fighting these kinds of wars for years. In 2009, PL lost all their territory and their super-caps (coincidentally while allied to GoonSwarm) and then turned around and re-built into a major player again.
Similarly, while it's a nice feather in CFC's cap it's not like this is them winning the final boss battle. Heck, relative to GoonSwarm's 2006-2009 campaign against BoB and half of EVE or the time in 2010 when they forgot to pay a bill and lost the richest 3 regions of the map (and all of their territory), this is barely a footnote in their history.
EVE is full of stories of large organizations that won the battles but lost the war.
Also, everyone should take heart what you said about lost ships. The best players only fly what they can afford to lose. Many of us players who did smaller-scale PvP had "rich-fit" ships just for comedy. Losing 25bil-fit frigates happens and most of us flew them because "fuck it" to begin with.
