Does a L2 solving all the developer experience/ergonomics make the L1 viable from a legal perspective? ERC20 doesn't come with explicit acceptance. Most of them get bridged into L2s, still holding visible links to pseudonymous accounts on entrance and exits, even if the L2 has asset transfer privacy in some form. Isn't that a problematic, inherent issue for the L1 if privacy is needed from a practical and legal perspective?
