What argument for condemnation? The government does not even compensate the owner for demolishing the building. It simply tears it down, bills the owner to haul it away, and leaves the land worthless.
I guarantee they don’t just walk up and start tearing homes down, these people were probably given years to bring their place up to code and ignored all the warnings. I have lived next to property that was condemned for being considered severe blight, there are times when nothing else will work with some people.
Don’t get me wrong. I am not saying the government was right. I am saying that of the few buildings I saw I could see, at a cursory glance, that a case for condemnation could be made.
When one lives in city limits, one accepts that there is a minimum standard of maintenance. Nobody wants to live next to a house that is a rat ranch. I remember a neighbor a couple blocks from me that got in trouble with the city for this sort of thing. They finally cleaned up his property and sent a bill.
If you want something closer to total freedom, you need to live in an unincorporated area. Even then, one must remember we do not live in total anarchy ANYWHERE in the US. There are very basic minimal rules.
