Immigration is NOT an individual rights issue when it comes to violating the laws of the nation you want to immigrate to. And you seem to think that immigration laws should benefit the immigrant, not the host nation. Unfortunately, you have it backwards.
As to your speed limit example: just try exceeding a school zone speed limit. Do it every day for a year. You see, entering our nation illegally is one violation; every day you remain here illegally is another violate. What do you think would happen to you if every day you drove 50 mph through a school zone? You would be enjoying three hots and a cot.
