The MAGA mob does not stand in opposition to or support of global finance capital, they represent the interests of assorted local notables and regional barons, the "beautiful boaters." Lots of large businesses have condemned the riots; the National Association of Manufacturers has even asked for Pence to depose Trump using the 25th amendment. A victory for the MAGA mob (assuming it would be possible) would merely be a victory of one type of capitalist over another, not the victory of capital writ large.
