I think it has pretty good solutions for those, but that's not the point. Blockchains are viewed as a way to make money from speculation, which is why the Bitcoin community is freaking out. Blockchains are actually a revolutionary technology for empowering users with applications they control. If Ethereum had the same sort of governance issue, it wouldn't matter. All of us developers would move our apps to whichever chain ends up being stable, because they'll all support the EVM our apps run on.

Ignore the speculation and build cool stuff.

Yes, but since no chain is 'stable' or has solutions for these issues, a developer should spend time building apps on their own blockchains which takes just minutes to make.

That's exactly what I do, and that's what I'm suggesting. Developers should read the docs, spin up a chain on their laptops, and build cool stuff.
