Developing crypto

So I hear a lot of talk about: What have you guys done with crypto besides trying to make money.

And I want to ask you guys, shouldn't the crypto community be trying to bridge real world physical things with crypto?

Example maybe a platform to resell old stuff like second hand iphones with eth, or maybe an airbnb style with less cleaning fees.

I try to view this crypto transition like what probably happen in china when they transitioned from gold to paper, people needed to use paper for physical things and services, and so we should build dencentralized services people need so they start transitioning.

What do you guys think good services would bring more people to use crypto if implemented with it
