https://microlancer.io is a great KYC-free freelancing platform (unlike Bitwage which requires government ID) and alternative to Fiverr and Upwork. Employers can post jobs, freelancers can post services, and reviews and escrow protect users against scams. You can also post jobs/looking for work ads in https://bitejo.com and https://bitcoinp2pmarketplace.com.
But merchants are also necessary: If you earn Bitcoin, you need somewhere to spend it e.g. grocery stores or landlords. It's possible to withdraw Bitcoin to cash without ID or a bank account, as well as buy store gift cards or KYC-free Visa gift cards with Bitcoin, but more Bitcoin-friendly merchants would help a lot.
