Did you try talking it out with your GM?

I didn't ask how do I deal with it, I asked why GMs keep doing it.

Lots of players say they want epic shit, grand, world shaking stuff. Lots of GMs think that is how games are supposed to go. Going from battling a few orcs near rivendel to Helm's Deep, then to destroying the dark lord himself

Fun fact: That's hard as fuck to run and turns things into endless escalation.

People are happier with a game that has a consistent scale and themes.

Because in order to keep a plot interesting and engaging, you have to change up the structure every once in awhile.

Note that this is not the same as escalation of the plot, but 9/10 people are too retarded to know the difference.

Also if we're talking about garbage games like DnD and it's derivatives, the players eventually becoming god-tier in terms of power as they gain levels kinda shuts down how engaging simple down-to-earth plot arcs can be.

The answer is levels. Levels cause problems. When you play a zero-to-hero one-to-twenty system, a natural narrative has to form from this.

If you start at level 1 in a system that says level 1 fights goblins and has to learn to get together and adapt to these rising challenge.

While goblins can be interesting for levels 1-4, eventually the mechanics push you towards being stronger and facing bigger threats.

By level 20, you have enough power that facing anything less than the god of evil feels like a waste of power.

Now, for systems outside of DnD, this is because DnD is the baseline and everyone knows a DnD story, so plenty of GMs (and hell, systems) put these structures innately into the story assumptions.
