I agree that weaponization of the courts as a tool for bullying, carrying out vendettas, and/or shutting down innovation from small companies is a huge problem (Donald Trump's penchant for this is one of the reasons I have a hard time closing the gap on supporting him). I think a good way to keep this system fairly stable but approximately prevent its weaponization is to require that each side has equivalently-priced representation. The Court should require the wealthier party to disclose their legal costs and pay 1x that much money into a trust managed by the Court, which would then be forwarded to the other party's attorneys. This way, both sides are evenly matched and it's a fair fight; if Thiel wants to pump $10m into the other party's legal offense fund, that's fine, but he'll have to pump an equivalent amount into the legal defense fund.
