You think we're gonna fight corporations as individuals if we strangle government?
No. Government is our protection from those who would want to consolidate power, especially corporations. I understand that the government often fails at that protection, but it's still a hell of a lot better than being completely defenseless.
The whole point of the founding fathers was to spread power and attempt to keep it spread. They wanted to avoid both the abuses of monarchy and the eventual decapitation of leadership (seeing as how that'd be their heads).
As someone who's self employed, I feel like self employment is a form of rebellion against this system.
My dad teases me that his socialist son is now a capitalist because I give music lessons and host events. I'm pretty sure I'm not because I don't profit from the labor of someone else, I do all the work and anyone who helps me isn't existentially tied to me.
If we're being honest, corporations don't "pay" taxes at all, those costs are instead passed on to the consumer. They collect taxes from you, just like the government, they just hide it better.
Self employment is very much not something you should seek. Self employment means the worker support all the risk. That's a boon for the capitalists. Why do you think uber and stuff are so successful?
