I hear this sentiment all the time. But as a kid, I first rode a bike with training wheels. The day my dad removed them, I went outside before him, hopped on the bike, and just started riding. There was no "learning to balance" or drama. I remember my parents were surprised but... maybe training wheels aren't so bad for everyone?
One thing I think gets lost in the discussion of training wheels: people act like you have four wheels flat on the ground, with no opportunity to balance. But proper training wheels should have two or three wheels on the ground, depending on if the rider is balancing or not. In other words, the training wheels should be lifted slightly up: https://www.twowheelingtots.com/training-wheels-faq/
I have seen kids learn to ride with training wheels. Basically the training wheels are raised relative to the rear wheel and the child learns to balance the bike on the tires, with the training wheels only touching when the bike leans over. But that only teaches them how to balance the bike when riding in a straight line. Not start, turn, or stop.
You might have been older, though. So with a balance bike you could've learned to bike years earlier. If you already had mastered balance, learning to bike isn't a big leap.
