The only ways we have to seize the means of production, currently, are:
1. Purchasing it with money.
2. Convincing the owner to share or reassign ownership of the means of production to the workers as a collective, as in a cooperative corporate model, and establish a democratic means of running the company.
3. Enacting laws through government to expropriate the means of production and then nationalize it.
4. Revolutionary force to replace the existing government and/or physically remove or occupy and defend the means of production.
