ETH fees at time of writing are about $1-3 for a transaction finality of < 60 sec. note that is fixed, the same if you transfer 1 or 100 or 1000 tokens.

though eventually as these networks scale most users will be transacting and interacting with L2 rather than L1. fees in L2 are in cents on the dollar, transaction finality is often very quick, and security assumptions are typically good enough for most use cases.

use case depends on consumer. paying for an abortion in a southern US state or paying a Russian or Iranian contractor for web design services might be a suitable example of crypto. paying for an in-game asset to avoid 30% App Store fees may be another use case in the future. or purchasing digital assets like art, domains. and smart contract functionality like escrow, auctions, loans and lending, global crowdfunds is another use case.

whether it is better or worse for each of those depends who you ask and what their goals are, and also in what year you ask. ten years ago it was inconceivable to do these things with crypto, ten years from now it may be that these systems will continue to improve in terms of fees, privacy, scalability and user experience. consider the current cohort of users to be beta testers who are taking on additional risk and technical burden while the system continues to improve.
