This is a useful notion if services and the maintenance of those services, is costly. The responsibility for that land then becomes totally yours. The only reason why the initial process of buying land is still in use is the idea of freedom. People want to feel and be free. Freedom means survival.
Survival means being free to choose to survive.
If the services are costly and do not meet your needs then you are limiting your freedom to survive. The more expensive the land, the more the idea of having 'fulfilled' the responsibility in some way. That change is then 'valued' according to the social conciousness. The social conciousness determines the amount of money one must pay for residency upon that land. The more immersed you are in social conciousness, the more the land will cost.
