Another issue I found is that creating blocks is quite time consuming, and it might require extra plugins to speed up the process. It all seems quite backwards.
Building custom blocks that can do all the things that can be easily accomplished using ACF would indeed be time consuming, not to mention requiring a new build process, both being more time consuming. This is another reason for not doing it. To make a profit building custom sites I’d need to increase my rates for a site to a point that I would have a hard time selling them and it would just put us out of business.
As you say, for simple sites, use gutenberg or some theme that uses gutenberg. People don’t need me if this is what they want to do.
