The author is a fool that deserves derision.
The Constitution has been amended with at least 26 changes through the decades...nearly 1 for every decade.
The author is actually arguing to disregard the Constitution in favor of direct democracy.
Over my dead body.
More likely in favor of judge-made law.
Yes, you want change? Then pass an Amendment to the Constitution. You want experimentalism? Then you should acknowledge that states can do that. Some states may want to legalize some things, others may not. That is experimentalism.
