A stack of papers going back years showing that the corporate entity you're dealing with confirms that you payed them on time for years feels a lot better defense than:
Me: your honor, I swear I paid them Corp: our computer thingy says you didn't. also it's a tangle of 50 different sql databases, so we'll never know the truth for sure
Similarly, if you have a bunch of paper showing that you did something with respect to the government that feels safer than officers showing up to your house because a database upgrade went sideways. Something is traceable. There's an artifact that can be used to reconstruct what really happened.
And the government needing forms can be useful too. If an internal auditor (or reporter or something) shows up and finds a bunch of filled out forms in the trash or they see that some forms are intentionally not replenished, then they can bust some skulls. However, on the other hand if things are just "lol the computer says you can't have freedoms and liberty" then maybe it's because of a bug with respect to the hyphen in your last name or maybe it's because someone is persecuting you illegally, but nobody can prove anything and there's no trail to follow.
