The reality is much much easier. You just google "I want a website" or "give me a .com" and click links until you get some free website builder or a webhosting company who will take your credit card and give you very easy to follow directions to choose a domain name and then takes you right into their online builder where everything is super user friendly and not much different than leaving a post on a social media platform. Most people would absolutely be able to get a website. It might be the best way to do it, but it would get done.
I expected you will go on with a joke how they will get scammed out of their money.
But then you went on and it made me think: people in question also trust these big name platforms. If they have just enough grit to try something on their own, they have, usually, enough of healthy view on themselves to know that they aren't sure how can they make this safely.
For a normal person, the only real words in this sentence are "get", "with", and "image", but the last one does not mean what they would think it means.
Even WIX needs some level of tech savviness, usually beyond 90% small business owners.
And Instagram? Well, one of the main points of having a restaurant is to tell your friends about it, so the Instagram profile is more important than actually having a real restaurant.
Make it 100%. I consider myself relatively "geeky", but I couldn't explain neither what a VPS or an nginx image is.
"Normies" are people who are not sure whether the photos they took today with their phone are "on the phone" or "in the cloud" or maybe on the laptop also? Or what?
Go from there to "nginx", I'll wait and don't hold my breath.
