The world exists to solely facilitate play and entertain the group.
I'd be surprised if anyone in the thread disagrees with that.
However, there are different ways to play, different ways the world can facilitate play, and different ideas of what's entertaining. Thus . . .
Which comes first, the chicken or the egg? The PCs or the World?
It seems one side arguing the world comes first and if its appropriate for the town to be attacked by hill giants the by-gods here come the rain of boulders, it doesn't matter if the PCs are powerful enough to face them in combat, they'll think of something or chalk it up to another lost town.
It doesn't matter if the adventurers are powerful enough to face them in combat if the encounter isn't about combat.
In this instance, the encounter may be about simple survival. Or about rescuing the villagers. Or saving a holy relic from the local temple. Or all of the above.
It may be about negotiating with the giants, offering them something they want in exchange for sparing the town. It may be about
outwitting the hill giants, luring them off, misdirecting them, not facing them down. And it may be setting the stage for the adventurers' return to drive off the giants later.
In my experience, if the response to everything in the game is swords and spells, the game gets stale very fast.

The other side is saying "but if the DM is going through the trouble of putting something there, then it makes sense the PCs should be able to handle it." There is no point in wasting time statting up monsters the PCs won't fight or creating scenarios that will either bore or crush their characters.
It's only a waste of time if you expect the only reason for creating encounters is combat..

While I DO agree powerful things should exist independent of PC levels (its not like giants magically move downriver and kick the orcs out now that the PCs are 10th level) . . .
That would actually make a perfectly valid motivation for the hill giants to in fact move downriver: the hill giants hear of the adventurers and decide to capture the adventurers, take their treasure, and ransom them to the king. Monsters can be proactive, too, and their intelligence can be as faulty as that of the adventurers.
. . . you have to agree that by-and-large PCs should face appropriate level encounters and receive appropriate level rewards, otherwise its OK to use Hill giants as a challenge for 5th level PCs.
I really don't have to agree to any such thing.
It's up to the adventurers to decide what's appropriate and what isn't. They need to be alert and use the resources available to them, magical and mundane, to survive. Sometimes they'll be confronted with opponents more powerful than they are; sometimes they get to tee off on some opponent that is laughably far below them. This is the nature of the world in which they live, and these are the consequences of the choices they make.
