It's not perfect but over the past decadeor two it's gotten incredibly easier year after year. I've been self-hosting much of my stuff since 2008. Since then, our technology stack has drastically improved. Home internet speed and reliability has improved. Networking products has improved to allow this to be easier. Compute power has increased to where you don't need to have a server rack in your house. If you don't want to, you can literally use a computer that's the size of your hand. And most importantly, the software stack has gotten so incredibly easy that you can self-host with the click of a button.
