This note is likely true. However, I think this can be applied not only Liquid but also to other blockchains.
Short version rebuttal:
Gold lacked scalability, which is why gold IOUs came into circulation and eventually gave birth to fiat.
I'm sure Bitcoin will follow in gold's footsteps if Bitcoin IOUs like Liquid become widely used.
Unlike LN, Liquid is not a layer 2 solution, but a testament to Bitcoin's lack of scalability.
