Maybe you're personally blessed with a super-strong immune system but what you're describing is not the usual common cold. A common cold takes around 9 days, and most people have to spend and are recommended to spend 3 of those in bed. Most common colds can develop into deadly pneumonia if you take them too lightly. A colleague of my girlfriend nearly died of one in 2018 because he ignored it and went out partying...
I don't know what to say except to appeal to my own experience. I've never heard of anyone I know being confined to bed by a common cold, nor getting pneumonia from one.
9 days maybe of lingering cough and sniffles, the worst of it is typically over in 3 days or so.

Which suggests a mild illness? (The cold, not the pneumonia). You literally can't go out partying when you are really ill.

The mild Covid experience described in the article was 36 hours - your own words. So it was literally like a light cold, as the physicians also confirmed according to the article. You're lucky that you've never had to stay in bed with a common cold.
Yes, my own words, but the worst of a cold and the worst of food poisoning (what OP compared the mild covid to) are, IMO totally different. The former is an inconvenience (headache, a bit tired, constantly runny nose), the latter is a totally debilitating state of never-ending vomiting and/or diarrhea. If you told me I was about to get a cold I would shrug, if you told me I was about to get food poisoning I would be dreading it.
There's no way we're going to come to a resolution of this discussion without additional data given our evidently very different experiences of what a cold is. All I can find is sources saying that colds are usually mild. But since this also called "mild covid", that resolves nothing.
