That is a sign they are ready to leave and reintegrate with society. Poetopia is not a place endangered of extinction through pollution. The poetry is recyclable. This leads to spiritual sustainability and metaphisical self-sufficency. Then people need less places to shop at but more places to write in, on, or at.
Places are build with poetry writing in mind.
Spaces for ideas, and human contact with the purpose to experience transformations. Buildings are designed as physical places that act as a springboard for the virtual space that only human interaction can achieve under the right circumstances. One kind of currency here is the well groomed word. These are in great demand considering the fickle nature of language. It takes a lot of effort to keep a word unspotted, unconnotated, uncommon.
