I didn't know this. Maybe merge mining could help us by easing the narrative of the security "they are as secure as they are in Bitcoin itself", but the block space won't be as scarce anyways.

neither are any of the altcoin chains yet they're still minting there too, they've even migrated the ordinals style of creating tokens and nfts into these altcoin chains like ETH, MATIC, doge and the list goes on. 

Sure they can justify a premium because you're using bitcoin, and it doesn't have the security label on the base layer like these other chains

That, and the fact that none of those sidechains are trustless, as long as there's a federation it's a centralized chain, and as long as it's centralized, minting the jpgs there is not worth it.
