No, you're just not grasping the difficulty here. Every time you introduce a new vocabulary word, you add cognitive load to learn that definition. Google "what is hosting" and you will get even more confused when they start talking about servers. Then they add extras: privacy guard, mail, SSL, even just getting a domain. To complicate things more, if you ask anyone vaguely technical for help, they will start talking about how you're getting ripped off and recommend S3 buckets and FTP access etc etc. These are not simple things; and I'm not saying all that to say oh, there's some idiots out there that can't do it; I'm saying this because when I built my own website, at 17 years old and with absolutely no CS background, my personal experience was that it was a very big learning curve and I think the average person just will not make it.
With a platform, you just... write. And it just works.
