Granularity increase and potential for theoretical pixel attacks. #21

Increase the granularity of of the land size.

Purpose: Increasing the granularity of Land to a smaller size will allow more flexibility for creating appropriately sized and shaped aggregate parcels.

Description: When combined with triangular/hexagonal grid, reducing Land parcel size will allow people to create aggregate parcels that have greater adjacency. This also allows for land to be more efficiently utilized conforming more tightly to the required use with less wastage. The increased efficiency will make it more economic for odd shaped use cases and micro uses.

In meatspace land parcel size and shapes have been constrained by the effort and expense of surveying and subdivision costs, these duties can be practically automatic in the virtual space. Meatspace parcel size/shapes were often shaped by irregular natural features which presented initial conditions from which interesting and aesthetically pleasing non-rectilinear emergent continuations propagated. Increased granularity and participants voluntarily non-rectilinear aggregate ownership patterns will result in emergent continuations of non-rectilinear features and aggregated parcel shapes that are inherently pleasing to humans.

Aggregating Land parcels into interesting shapes can occur even if parcels remain square so long as the granularity is sufficiently micronized.

With 1000 mana = 1 land the potential exists for parcels 1/1000th the current size to still be purchased 1=1.

The base layer should be as flexible as possible but this may present an attack surface by allowing theoretical Pixel attacks. In a pixel attack the attacker purchases many non contiguous single micro land units spread out in a manner so as to disrupt usability of all the interstitial spaces. This attack could be minimized by the economic incentives as the attacker would be bearing a cost. Meatspace equivalents of attacks like this have occured in places where people wont sell small parcels, easments or airspace or where people deliberately purchase such to impede a development. In the virtual world this attack could be deployed on a much larger scale rapidly given sufficient resources.

I should have also mentioned having a means for consolidating and subdividing parcels.
