What is the appropriate punishment for Aaron Schlossberg's actions?

69. PSPS is correct as to many states

In New York, where Schlossberg practices, your explanation is correct, as I set forth in excessive detail here. New York has what the Wikipedia article on "Bar association" calls a voluntary bar association, so Schlossberg needn't be a member to practice.

According to that article, however:

Some states require membership in the state's bar association to practice law there. Such an organization is called a mandatory, integrated, or unified bar,[3][4] and is a type of government-granted monopoly. They exist at present in a slight majority of U.S. states: Alabama, Alaska, Arizona, California, Florida, Georgia, Hawaii, Idaho, Kentucky, Louisiana, Maine, Michigan, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, North Dakota, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Texas, Utah, Virginia, Washington State, West Virginia, Wisconsin, and Wyoming. The District of Columbia, the U.S. Virgin Islands, Guam and the Northern Mariana Islands also have unified bars. The mandatory status of the Puerto Rico Bar Association was eliminated in 2009 by an act of the legislature, ratified by recently appointed majority of the Puerto Rico Supreme Court. By act of the Puerto Rico legislature, the mandatory status was reinstated in June, 2014. The Supreme Court of Puerto Rico struck down this act in October, 2014, finding that it unconstitutionally usurped its powers.

In some states, like Wisconsin, the mandatory membership requirement is implemented through an order of the state supreme court, which can be revoked or canceled at any time at the court's discretion. In others, like Oregon, the state legislature passed a law and created a government agency. California went farther than any other state and wrote the State Bar of California into its constitution.

The first state to have an integrated bar association was North Dakota in 1921.[5]

So now you have a list of states not to move to.
