This is a fantastic article, it does miss one very key point about bog-standard HTML which is worth mentioning though.
The standard widgets are all accessible, people with screen readers, limited mobility, poor vision, etc, all rely on pages being written so the devices they use to read the web can function properly. People who choose to eschew these standard components very frequently end up with a site which is unusable for disabled people.
Very few people have the skill to turn a div into an effective button, yet over and over I see web sites with rows of buttons which are in fact just divs with javascript behind them.
Making your site accessible isn't just a good practice, in the US, it is the law. Courts have ruled that the ADA applies to web sites along with any other type of business. A small sample of sites where people thought they could smash together super-fancy sites without concern for basic needs of users: https://www.atilus.com/top-10-ada-lawsuits/
