Legalization usually implies allowing some degree of commercialization, otherwise you end up with weird middle ground like Netherlands. What Germany is doing isn’t even going as far as Netherlands do, at least for now since there are going to be pilot programs for small scale shops (on top of currently proposed clubs).

US is vastly different from state to state, ranging from cannabis being illegal, through medical use being allowed with varying degrees of ease of prescriptions, all up to full legalization including commercialization.
