There are glimmers of hope - like Wales trying to ban lying in politics. But of course, the punishment has to be proportional to the offense, not just a slap on the wrist.
If I wanted to take things to an extreme, I'd ask why laws even need to be so specific about which offenses lead to which punishments and which offenses are even punishable in the first place (the "what is not forbidden is allowed" principle).
In theory, you could cover them more generally by saying that any time someone intentionally causes harm to others (without a valid reason), he will be caused proportional harm in return. Then all you need is a conversion table to prison time, fines, etc.
With lying, all you would need to prove is that the person lied intentionally and quantify the expected harm which would have been caused if the lie was successful (regardless if it actually was or not - intent is what matters).
As a bonus, it would force everyone to acknowledge the full amount of harm caused. For example, rape usually leads to lifelong consequences for the victim but not the attacker. In this system, such inconsistency, some would call it injustice, would be obvious and it would be much easier for anyone to call for rectification.
You don't have to lie to tell a lie. The media have honed well this skill over decades.
"Coffee study found that it TRIPLES, your chance of developing a terrifying form of colon cancer! A 300% increase!"
In reality the study had a sample size of 10 and the odds were for an extremely rare form of lung cancer you have a 0.0003% chance of developing anyway. But now most readers go tell their co-workers "they did a study and found that coffee actually gives you colon cancer".

Lol. Give me a break. This is like all the "combat disinformation" bullshit. You claim something is a lie or disinformation because your government appointed expert said so and jail someone. When years later it's undeniable that you were the one lying you said "we did the best with what we had at the Time".
Naive solutions only give more power to those in power and are abused routinely.
"without a valid reason" is doing a lot of heavy lifting here. Not only would this idea be impractical and highly subjective, determining what a valid reason is, is the same problem as defining the Law in the first place.
Can you insult someone? Can you say something wrong that you thought was right ("the lion cage is locked") that someone is injured from? What is their duties in checking the info they get is correct? Is there a min wage or not? What value is it? Does it change on city or state? Can under-age people sign contracts? Can they vote?
Obviously we need the law in any practical world.
