Monopolistically competitive firms typically comprise a large proportion of the economy and are therefore troublesome to regulate due to their sheer number.

Regulating them could also be troublesome for the economy as it might reduce the options that consumers have as well as exacerbate the inefficiencies of said firms.

They are not however, virtually untouchable as there are a myriad of laws that enable the Government to regulate them if the Government feels it is in the best interest of the consumers.
