So instead of moving toward changing the minds of those who are indirectly benefiting from the 'slavery', we just go out and beat them up? (Since we can't punch the slave masters...)
Who do you think these people will join after that? The slave masters or those who want to free the slaves?
That's a lie.
Do what you will. Expect consequences. If you're rational you will anticipate correctly. You seem to be irrationally expecting there to be no negative consequences of unethical profiteering.
I hope you learn from the unexpected results you experience, and that gaining wisdom profits you more than losing money harms you.
