"buying land and settling it is just buying land and settling it."

As though, if you can afford it, it must not hurt anyone.

Consider a hypothetical situation:
There is a natural disaster. As a result, most stores are short on food for a while.

A man who has plenty of money has an emergency shelter in place, well stocked.
He is out during the day, his shelter locked up, and he comes across a store which has some food, albeit at higher than normal prices.
But they have a limited supply.
He could just walk home, but he is hungry now, so he buys some bread and eats it.
Which means someone else can't.
He is just buying something and using it, and he can afford it - but it is still immoral.

Another example, a real life one this time.

I used to live in a trailer park about 15 miles from Manhattan.
In that area rent for even a small apartment can be over $1000 per month.
Our rent at the park was $420 a month.
It was affordable, and it was totally unsubsidized.
Some residents were retired, some disabled, some young, some with families, some working poor. The majority of the residents could not afford to more than double our rent. There were about a couple hundred households between my park and another one next door.
There was no other comparably low cost housing in the area.

The city government wanted to, under the eminent domain ruling, force the parks owners to sell, and then re-sell the land to private developers who would put up a strip mall in its place. The rationale was that the mall would provide more tax revenue to the city. Economically, as long as they compensated the land owners, they would have been in the right, but it would have still been immoral (I don't know what happened, I moved out of the state).

Suppose Phillip Morris can afford to put cartoon ads for smoking on during Saturday morning cartoons. Would that be ok? Its just buying and using advertising slots on radio wave frequencies.

Suppose wealthy Islamists want to buy the Washington Monument, Mt. Rushmore, Yosemite and Yellowstone Parks, and the Golden Gate bridge.
If they can afford it, do we let them?
Suppose someone wants to buy the house you live in as a renter, and throw you out.

In the REAL buying land and settling it is NEVER just buying land and settling it, because anywhere you go in this country, someone already lives there.
Go find a Native American and ask them if "buying" land and settling it is "just" buying land and settling it.
The pioneers bought the land they settled from the US government.
Only problem is, it wasn't rightfully theirs to sell.

Little wonder that the citizens of a country built on this practice would support Israel for doing the same thing.
