How many of those van-traveling green card holding construction workers have been fined or imprisoned for failure to carry the green card lately? I don't mean brief detention - anybody can be detained by the police, especially when not having any identification - I mean actual conviction under 1304(e) and court-assigned fine or jail time. How many such cases do you know?
To put it another way, the $100 fine is less expensive to me than the consequences of losing it.
I'm guessing there's no size requirements? If so it might be a good idea to just print four on an A4, and have one folded in your wallet, one tucked in your bag-pack, one in the car, etc.
This is a new development (well, new-ish for many communities... I imagine predominatly-black communities have always experience this) whereby LE is explicitly instructed to look for any legal course of action to punitively enforce the law (rather than using a more judicious interpretation, which was more in line with the spirit of many of these regulations).
So yes, technically, law-abiding citizens should always xxxx. Does that mean that, in real life, folks always do this? Only if they are in a paranoid state whereby LE maliciously enforces the law for any minor violation and enforces overwhelming (often illegal) responses to these infractions.
ICE operates in every state. e.g. US citizens are being jailed in California (https://apnews.com/article/us-army-veteran-immigration-raid-...)

Still to your point of a state government authority calling the feds because someone they interacted with looked Hispanic.
To be more specific:
>> (e) Every alien, eighteen years of age and over, shall at all times carry with him and have in his personal possession any certificate of alien registration or alien registration receipt card issued to him pursuant to subsection (d). Any alien who fails to comply with the provisions of this subsection shall be guilty of a misdemeanor and shall upon conviction for each offense be fined not to exceed $100 or be imprisoned not more than thirty days, or both.
Where evidence of registration is an I94 or a green card or whatever.
I’m constantly surprised how many permanent residents don’t do this.
