I agree with eliminating the need for lawyers for most things, but the biggest problem about it is that in small cities/towns (maybe big ones too, I just have no experience in that domain) judges and lawyers are "buddies". People with the exact same charges can get radically different sentences depending on if they have a paid lawyer vs no lawyer or a public defender. There's a public defender in my town who also has his own private firm, and it's amazing how differently the judge and DA respond to whether or not you hired him or the town did. If all of that isn't bad enough, you can see the judge, DA , and lawyers all making backroom deals and exchanging favors. And they do it fairly blatantly in my town. I've rarely seen an objective case and it's a shame because law is perceived as a "sacred" domain where objectivity rules.

So you don't agree that 'the person who represents themself has an idiot for a client'?

If you're going to court, bring a lawyer. Courts are the domain of arcane procedures and common sense has no place there. My comments above refer to transactions, compliance, etc.

Probably smart to bring one to court with you but maybe not required for drawing up a standard will where the few assets you own should just go to your next of kin

Lawyers write human readable code that's compiled and run by a judge or interfacing APIs (institutions such as financial ones)

Your advice is akin to saying "hey you inexperienced coder, write some production ready code but don't test it and when the only time it needs to run, give it a try. Hope you don't screw it up! When there's another coder in the room who can claim 'oh no he meant to set my financial variable 100X not 10x' and can convince the compiler to agree with them"

This analogy falls apart pretty quickly. You can't compile legal work product and no one is accountable if it doesn't run, unless you're at the point where malpractice comes into play. Malpractice is really, really hard to prove, though.

But most judges are making subjective decisions and not just "running code". The US constitution is law; can you compile it into code such that a computer could tell you whether a particular piece of legislation was unconstitutional? If you could, why hasn't such a computer replaced most of the US Supreme Court?
