There are plenty of online platforms that offer self build. You use their software, upload your content, choose your colours and there it is. Easy!
As long as you're happy with the options they offer you.
But have you ever wondered what would happen if you grew out of their limited software? What if you wanted to innovate or if you didn't like their hosting?
What if (heaven forbid) that company ceased to exist?
WordPress software is open source, which means it's not tied to one company. You can keep a copy of your site, so you really own it. If your hosting company doesn't give you what you need you can choose another. If your business grows and you need functions added no problem... you could even get them written especially for you.
But freedom brings complexity. Before you know it you're wandering in a baffling jungle of DNS and API's and caches, away from the real business that you love.
