New Internet... ETH is fuel?

Hello all, can someone please explain this concept to me, and why this would be mass adopted. I’ve heard it said that Ethereum is the new Internet, and eth is the fuel for it. Considering for our current Internet you can pay a small monthly fee for unlimited usage, I’m wondering why people would use a new Internet that has significant fees to use for almost everything that will be done on it.

Can some one help me to understand how that will ever be adopted? I’m not sure anyone really prefers to pay per use, and would prefer an unlimited use option.
