Or a "Chef" serving microwave ready-meals.
There may be a case for where you draw the line. Many developers use pre-made things to save time and effort, be that themes, templates, CMS, frameworks, plug-ins, modules, libraries, etc. but could still be true developers.
I've not looked closely at things like Wix, so don't know exactly how much work/skill/knowledge/time one needs to set them up, but if the adverts are to be believed, not very much at all.
Returning to the food analogy, Wix/Squarespace are microwave ready-meals. Someone with little ability or effort can produce something in very little time, but the quality is not great.
I would say the likes of Wordpress are like McDonalds. Very popular, people lap it up, but not particularly wholesome and you may find yourself carrying a bit of excess bloat as a result. The people in the kitchen may not be top of the skills tree, but you know what you are getting and won't have to wait too long for it.
Or you can go to a restaurant and have a trained chef prepare a meal by hand. It will probably take longer and cost more. The results may be anything from exquisite to bang-average, depending on where you go and what you pay.
And then there is home cooking. That takes time, effort and ability, if you have those things, the results will be as good as you are at it.
So you have a trade-off of convenience and cost over quality.
I don't know, there may well be people out there wanting to make a quick buck, charging people to have them make sites like this. The client may not know any better.
But would you be happy to pay someone to nuke a plastic tray for five minutes for you, just to get a mediocre meal?
