Every instrument (brass, woodwind, even a simple triangle), past a certain threshold is expensive, and their sound is different to their lower priced peers, and yes, you can't equip every violinist with a $2MM violin, just because.

Also, saying that instrument X is higher caliber to instrument Y is completely wrong. They all needs immense workmanship to produce, and immense effort to play. This effort can't be compared. A double bassist's finger spread for the first three positions is almost equal to whole keyboard/fretboard of a violin, but a violin can play 8x more notes with a bow when compared to the double bass. Momentum is a strong adversary when you try to change direction with a full size German bow.

You might think woodwinds are easy. A French horn player needs to play adjacent notes with small lip movements. That's an unforgiving blade's edge. A tuba player needs lungs of a whale to keep that long notes, etc. etc.

Also, just because viola, cello and double bass looks like a violin is borderline insult to all of them at once, and ignoring the other heavy lifters like clarinets, oboes and fagots.

Like how the article outlines. An expensive violin is good for a solo performance, but loses its importance in an orchestra. Like how F-35 becomes the wrong thing when the theater of war calls for different conventions and operates with completely different dynamics.

P.S.: Yes, I have played double bass in a symphony orchestra.
