You are confusing capitalism with competitive markets. Capitalists want to make money off their capital, they don't care it's through competition or rent extraction. Having a monopoly is much less work than competing so that's probably the preferred way to make money. Capitalists also historically didn't care about democracy, dictatorship or corruption as long there was money to be made.
