Partially I think this is a question of what you mean when you say "app". There are millions of websites running Wordpress, plus maybe a specific plugin to do e-commerce or something. They are very close to the ideal you are describing. There are also millions running on things like Shopify, Wix, etc. Usually these kinds of things are not really made by developers, or at least only require a very small amount of development time. It's only when we get to the more complex 20% of applications that we start having a "problem". So I think when you talk about most apps being basic, you're right. Excel allows people to do in 10 minutes something that would've required dedicated applications built by trained professionals 30 years ago. We're just not stopping there.
