Well you are ignoring what I or the other comment replied almost entirely.

There were many competing standards and it took quite a while for the market to converge on usb-c and only then when it was already the most popular connector by far did EU determine it was the “best” standard.

Firewire, Thunderbolt 1, all kinds of different usb type ports where designed by various groups of companies it was not self evident that they will fail in the market at that point.

No industry group let alone an EU committee can know what will fail or succeed in advance its just an absurd assumption that it could ever be otherwise.
