Think of Bitcoin like a highway.
PoW is the friction.
Just like a car needs friction on the road to move forward safely,
Bitcoin needs miners competing with energy and work.
That friction makes it very hard for anyone to cheat or take shortcuts.
It keeps the system honest.
Fees are the filter.
Imagine a tollbooth that only lets through the cars willing to pay.
When the highway is crowded, only the cars that value the trip the most will pass.
In Bitcoin, transaction fees make sure that only the most important or urgent transactions get included when space is tight.
So friction (PoW) keeps everyone honest, and the filter (fees) makes sure the system is used fairly and efficiently.
