This story dives into the effects of forking and altcoins in a bitcoin world. Those who lived through the block size debates and bitcoin cash forks will have some personal experience here.
A fee market has developed for transactions ranging from one block to one year of blocks. Most all transactions happen on layer two networks. Smart contracts and DAOs are prolific mostly running on lightning rgb and and rsk. The world Mars and Venus's governance systems are all on the bitcoin blochain.
Forking causes transaction surges. The prospect of these fee surges tend to cause some "public political" main net coins to indicate their fork choice and implementing forked coin sell-offs quickly to reduce their utxo's and loose anonymity in the process. Since information is very free and dispersed and the world isn't exactly a utopia this is a big disadvantage.
This exposes large and political organisations to various risks and over time this political behavior is reduced. So we have more forks and fewer people selling these forks early on. The prices are more stable and so this propensity not to sell forks immediately adds to the money supply.
So we have a natural process where when there is disunity in the bitcoin system we get a short theoretic doubling of the money supply, one bitcoin for each side of the argument. Though many people will not intend on collecting this money. This disagreement is more common when the economy is not working well or when society is under stress. So it tends to happen at a time when resources are needed but when the actions needed are unclear.
As people who are neutral, unclear or private will tend not to want to move their coins this could slow down the economy. Counter to this people with strong opinions, through the forking can get an opportunity for a financial boost. They would need to make it work quickly though as when both forks have perceived value and they are trading within their forked group with the new forked currency then the money supply increases and the economy can speed up.
Consider in 2140 that the human race is interplanetary and we are beginning to explore nearby solar systems and the resources required for exploration might stir up debate. Some people may want to put a lot of resources into covering the galaxy with human beings, others may consider this risky and destructive of nature. So politics develop. People at this stage have seemingly almost unlimited resources. Bitcoin can not control the people and what they do, so many people are just building rockets. Others who don't want this start to devote time to convincing people that this is unwise or leave to form a separate society.
So on Earth we have politics between noninterventionist naturalist who want to be conservative at home and spendy explorers. They decide to separate financially and so we get a bitcoin fork for the spendy explorers and as you might expect it has slower blocks. Both forks hold value ok for a few years. this means that we get an increase in the money supply and its great we can fund a good amount of explorations.
Over time the "spendy explorers" need funds to implement their expansion so at first they sell more of the opposite fork. Naturalists and in-betweeners hold both forks as it seems that the exploration is not all bad and could prove productive. Initially, let's say the unchanged "naturalist" bitcoin fork drops in price more than the explorer coin, but as explorations projects start taking longer to work out, explorers double down on their plans and end up selling their own coins to get their agendas done. Explorations expand to the point where it's not practical than the "explorer" coin drops. Everything comes back into balance.
