Do you agree with the idea that “no one is illegal on stolen land” when referring to illegal immigration to the US? Why or why not?

For context I answered this question on Quora

This is an idea only entertained by economically illiterate morons who think countries are reducible to land. Unfortunately for them reality is not that simple. With the exception of farmland, the value of any parcel of land has jack squat to do with the actual soil or who lived on it thousands of years ago. Its value is contingent on the quality of the infrastructure built around it, its proximity to certain amenities, the quality of the education your children could receive in the designated school district the land is situated in and the income advantage of having access to job market around it. The goods and services available around the land, which includes public goods and services, is what makes it valuable, not dimwitted tribal people who can’t advance past the stone age. So people who take advantage of a country because of what made its land valuable to the rest of the world and commit identity theft and fraud against its citizens to gain an economic advantage not available in their homeland are in fact illegal. And the jurisdiction established on that land is the final arbiter of determining what theft is. You do not get to have your own personal statutes.

The Mascho Piro show us what the Indians would still be doing if the white man never arrived. Running around in loin cloth, chucking wooden spears/arrows at unsuspecting animals and living in thatch huts. No animal husbandry, no ironwork or metallurgy of any kind, no sewage and water treatment, no modern medicine, die from easily preventable noncommunicable diseases like tetanus and meningitis (no vaccines) and have childhood mortality rates 100x higher than today. The North American land mass is 10 million times more productive today because of European colonization. Even the more advanced tribes like the Mayans and Incas were very unlikely to reach the industrial revolution as they only reached the bronze age before their collapse and did not readily mine coal. If the U.S. did not exist the world would be substantially poorer, billions would have perished prematurely from diseases and conditions treated by U.S. medical innovations and you wouldn’t be bitching about things that happened 2 centuries ago on the internet. There would be no internet without the U.S. From the big picture perspective, colonialism was a net positive.
