- Bitcoin offers a transferrable store of value which cannot be inflated by governments,
- Stablecoins, thanks to being cross-border, are often used in e.g. Argentina where the local currency is unstable and it's not legal to buy dollars,
- Proof of Humanity + universal basic income has provided extra income to Argentinian people (e.g. heard of someone who was able to purchase a ticket to visit their family for Christmas thanks to crypto UBI),
- Crypto has been used to send remittances to economically unstable places (Lebanon, Turkey, Venezuela)
- Gitcoin has provided public goods funding and advanced our conception of mechanism design,
- Helium has created a new 5G network that people can actually roam onto,
- NFTs have provided a new funding model for artists (who create public goods),
- Zcash and Monero have allowed for fully private digital transfers,
- Dark Forest (https://zkga.me/) has been an amusing game,
- Snapshot has helped create a delegative voting system that governs a $3B treasury,
These might not be problems that you face or believe are important, but all these are examples of intended problems being solved.
P.S. the tone of your comment made me a little sad :(
