I recently heard a remarkable interpretation of the symbolic significance. The crown of thorns needs to be viewed in a Roman military context: from Wikipedia:

The grass crown

• (Latin: corona obsidionalis or corona graminea), was the highest and rarest of all military decorations. It was presented only to a general or commander who broke the blockade of a beleaguered Roman Army. https://en.wikipedia.org/wiki/Grass_Crown

It's important to note that "it was presented to the general by the army he had saved".

Since the Roman company of soldiers mockingly presented this to Jesus, they unknowingly declared that he has saved them.

Pliny wrote about the grass crown:

(…), but as for the crown of grass, it was never conferred except at a crisis of extreme desperation, never voted except by the acclamation of the whole army, and never to any one but to him who had been its preserver. Other crowns were awarded by the generals to the soldiers, this alone by the soldiers, and to the general. This crown is known also as the “ obsidional ” crown, from the circumstance of a beleaguered army being delivered, and so preserved from fearful disaster. If we are to regard as a glorious and a hallowed reward the civic crown, presented for preserving the life of a single citizen, and him, perhaps, of the very humblest rank, what, pray, ought to be thought of a whole army being saved, and indebted for its preservation to the valour of a single individual?

The crown of thorns can be viewed as a grass crown in that: (a) the whole company presented it to Jesus, same as the whole army presenting a grass crown, and (b) it's the only award that can be given by the soldiers to the commander.

Remarkable....
