I don't think you can compare LEGO with not-LEGO...
Firstly it feels a little sacrilegious, but religion aside quality is often uncomparable and there was this common meme from my childhood that your parents did not love you if you got knockoff LEGOs. Part of the reason why we buy LEGO is because it's LEGO. Buying some other brand (regardless of quality) does not hit the same way.
But that's a learned behaviour, and one learned specifically thanks to decades of marketing. Sure, LEGO is quality, but it's not some unbeatable gold standard. At some point it simply becomes one of those things where people ask for Coke instead of Pepsi, even if they can't tell them apart - brand loyalty trumping the desire to simply get the product.

I am not sure this is an accurate assessment. Lego has a reputation because it built that reputation over decades of solid and reliable delivery. Pseudo-Lego brands built a reputation of competing on price while trading off quality and reliability.
The real question is whether the price delta between Lego and pseudo-Lego can justify the quality delta. That's surely subjective up to a point.

Really? I'm not sure about that. I think LEGO built a reputation, because it was patented until 2008 and competitive products were not even a thing.
Mould King was founded 2012, also more than a decade ago.

This maybe true for chinese rip-offs, but the more modern approach is innovative, even with licensed models (see CADA MASTER Mercedes-AMG ONE 61503 or Mould King 12025 Orient Express). Features like LED lights, remote controls, remote controlled doors or REAL steam have not been approached by modern LEGO sets.
Where did LEGO have a patent? It certainly wasn't the US. Mega has been here for decades. LEGO tried to sue them under copyright law but lost. My experience with non-LEGO bricks has been extremely mixed, averaging negative.
I think the "LEGO tax" is as much about consistency as marketing inertia. With name-brand LEGO, you know what you're going to get quality-wise. Alternative brands can be unpredictable. I would know; I still have all my LEGO from when I was a kid, and since my family isn't made of money, a lot of them aren't actually LEGO.
Alternative brands can VERY hit-or-miss, and when you miss, you can end up with some truly atrocious pieces. When I was a kid, Mega Bloks was the most common LEGO alternative (in the US, at least), and all of those pieces are terrible. The colors are washed out compared to LEGO, the plates aren't as rigid, and some of the bricks are a mess of scratches and dents.
Consistency is even a problem within individual sets. I also had a couple of LEGO-compatible sets that were made by Hasbro in the mid-2000s, and the part quality is excellent. The pieces have held up really well over the years, and Hasbro's yellow pieces are indistinguishable from LEGO's yellow. Hasbro came correct... except for their wheels, which are the sort of hideous dirt-cheap abomination that even Mega Bloks never stooped to.
Some brands are awful. Some brands are great. Some brands (like Hasbro) somehow managed to put "awful" and "great" inside the very same box. A brand's quality may change wildly over time. Some brands come out with their own extensions to the LEGO "standard," and then never provide a complete system of compatible parts. Sticking to name-brand LEGO offers a much more predictable experience.
A local toy store here has one set of shelves filled with Sluban (about ⅓ the size of their Lego offering), and it's just bleak to see. The shop focused their Sluban offering on military hardware for some reason (perhaps because Lego doesn't do any of that), so you end up with drab boxes of greens and browns, in addition to looking just off in terms of accuracy of the parts.
There's also a bunch of the 'fake' stuff on AliExpress, where you can tell the quality of the bricks is crap just by looking at the low-res photos. Getting the fit of bricks right is apparently quite hard to do if you want to offer lower prices than Lego does.
> I think LEGO has done a great marketing job here... never buy something that is not LEGO, it might be bad quality or scam.
I don't think that was LEGO. I think that was just the off brands being pretty university awful and people caught on.
I'm going through a bucket of loose parts right now, separating the off brands from the LEGO. There are at least 6 different brands in there. The difference is almost always obvious.
And when it's not and the part sneaks its way into my main collection, I can instantly tell when I use it because it either doesn't fit, or fits incorrectly.
