The article is specifically talking about internet-based companies, aka "tech". It seems to me you're confirming an absence of them, which to me invalidates your comment of 'who said unicorns are good?', because the absence suggests that the current model isn't working.

It's true the world isn't the US -- can you point to successful internet-based EU companies that are big in both EU and some other part of the world? If so, it would seem a shame that they're not able to compete well in the US given the size of the market and the compatibility in culture/law/trade.

He asked for valued products. Not valued tech products. With the hidden assumption, which I called out, that only products created by tech unicorns are products.

And pithy one-liners are not arguments. OP is specifically asking for examples.
