No i mean the consequences if ordinals dies down. then there was less than a year of monkeys and then they're gone. do the existing monkeys cause a long term damage on bitcoin or something? the blockspace used would have been the same no matter if its for monkeys or paying bills.
Its bloat that wouldn't have otherwise been there. Its not so much (right now) in the grand scheme of things, which is possibly one of the reasons why Core devs have been reluctant to rush out any changes, but the smaller the blockchain stays, the better. The less resources that are required to run a node, the better.
You can see growth of the blockchain was relatively linear up until early February of this year, which is when the Ordinals fad really started to kick in, then it sped up since then:

Zooming out, blockchain size growth takes on more of an exponential quality but there's no reason to hasten it.
