Evidence is clearRothbard no longer significant 

Looking at the Journal of Libertarian studies' ranking of the most influential economists, one can see that Murray Rothbard is no longer considered significant among leading libertarian economists.  He fell off the top 10 ranking 2 years ago and has not been back since.  Again, I urge you to see the Journal of Libertarian Studies' ranking of the 10 Most Influential Libertarian Economists.
