Personally I’d try by enforcing an exchange - limited liability status for speech restrictions - that way people can still “organize in corporations” - unlimited liability ones - but if they want extra privileges, they have to give up some of their rights. If that won’t work, yeah, constitutional amendment. Although there definitely exist a number of regulations that effectively restrict corporate speech - e.g. anti-terrorist funding legislation - so probably there’s other ways to do it as well.
