Not only am I dead serious, I am also right. :)
Most of the 'problems' you speak of are problems of socialism, not immigration. Priorities.
Some thoughts on the subject:

The only valid point you make, IMO, is regarding terrorism, the borders need to be secure for that.
Debasing Reagan's speech. Nowhere does it say illegal alien.
To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;
To establish an uniform Rule of Naturalization, and uniform Laws on the subject of Bankruptcies throughout the United States;
To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;
From the Constitution. Congress has always had the power to regulate immigration. It has not needed to grow bigger to do so.
In your world are there any borders? If not, why not?
So if someone wants to set up shop on the street and sell moonshine or homebrew for cash, too bad for the liquor store that has to buy LEGAL booze and pay sales tax.
If one grocery store buys meat directly from a rancher, too bad for the stores that have to buy it LEGALLY from the slaughterhouses where it's FDA approved.
And I guess we should just let Merck sell whatever they can put on the drugstore shelf of their own free will.
Maybe we should allow thieves to take whatever than can get out banks of their own free will.
Or allow rapists to have at any woman they can grab of their own free will.
Who needs laws and borders? They just cause problems of socialism...
