Yes I get OP_VAULT wouldn't make sense on Liquid

I guess for ordinals, yes the block space and fee paid is the value prop, you could do your stupid mint/etch transaction on base and then move to the multi-sig where you go and trade, just so it reduces the need to always use block space for it

Retail who tend to get involved in this stuff are always looking for cheaper options, otherwise TRON, MATIC and other offshoots of EVMs wouldn't exist
