The technology to realize a peer-to-peer alternative to GH is here. We just need to make it happen. IMO radicle.xyz is the most promising one right now.
The only path that makes me hopeful involves a combination of 1. FOSS software (ie forkabke when the warlord misbehaves) 2. user owned / governed networks, so the warlord can't easily get extractive against their users.
You are forgetting the importance of open hardware, in ideal world we shouldn't need to install Libreboot to fight proprietary drivers and firmware that can be turned against you any second.
To add to that: there are several major stablecoins on Ethereum: USDT, which is backed by BitFinex and has $12 billion in circulation, USDC from Coinbase/Circle with $3 billion in circulation, GUSD, from Gemini, BUSD from Binance with $700M in circulation, and DAI, which is decentralized and has $1 billion in circulation.
These are all ERC20 tokens so easy to integrate into Radicle, and offer a way to allow developers to get paid peer-to-peer while completely avoiding the price volatility of typical cryptocurrencies.
The fact that they assume that decentralized web equals immutable and global by default shows ignorance. You should take a look at SSB and Radicle, if you want a different dweb than IPFS.
