What I'm missing is where a collection of static files couldn't just be served up from an S3 bucket and Cloudfront or Cloudflare on the front end -- you arguably have the same caching performance if not better since Amazon and Cloudflare have real SLAs for getting your bits from your bucket to a user's browser.
IPFS seems like un-needed complexity when there are a huge amount of options available. If you personally don't like Amazon, you can use Github pages, or DigitalOcean, or Netlify, or Fastly, or the list goes on and on.
Does anyone have a use for IPFS that isn't already covered by existing hosting+cdn options?
