This particular post branches off two threads:
First, I'd like to discuss this "murderhobo" nonsense that's referenced, however jokingly, and why I despise it.
Adventurers in the worlds of fantasy are typically played as relatively good, first off. Even the most chaotically good character is going to respect some degree of societal boundaries, and the creatures that they fight are going to be fought due to self defense, defense of the citizenry, or defense of Creation itself. They do not, despite the meme, go around murdering anything that gets in their way, unless they want armies marching after them. The only characters that could truly, honestly be considered murderhobos are assassins.
Also, not all adventurers are homeless, and there are plenty of ways to get established characters with entire kingdoms to their name to come out and adventure. After all, even the Chief of Police will head out with the normal patrol officers to bring a high-profile criminal down. That's what high-level adventurers with strongholds and bases are - the ace in the hole. They go after much bigger game, and at high enough levels, will only be drawn out for game that few have ever even heard of.
The second thread ties into the first a bit. There's a L&L article that states that ost people don't adventure beyond tenth level. While I will admit that most of my adventuring has been done at less than high levels, I've also played plenty of campaigns up in the stratosphere, where fighters doing tens of thousands of damage on a lucky crit is not unheard of. Who are these people that abhor high levels? I don't doubt that they exist, in fact, I prefer starting campaigns in any system at first level, and find that I generally enjoy lower levels more in some cases.
That said, anyone who doesn't like high level shouldn't really have a say in whether it exists at all, or how it's handled. It's kind of like weapons IRL - don't like them, fine, but keep it to yourself and stop trying to limit my access.
