I have never heard a convincing answer....

Why would anyone buy on the eth network?

If I owned a gas station and every transaction for fuel/groceries I had to charge pennies on top of the transaction and my competitor across the street charged tens of hundreds of dollars on top of each transaction my competitor would be out of business quickly.

Why is eth still around and how? I would think just plain competition would have wiped it out.

Not fudding or complaining, just trying to understand why its still going strong with the fees it has. Thanks all.
