Is that a joke?
Bitcoin is basic maths. Making laws to change how Bitcoins work is like making laws to change how gravity work.
Guns and bullets run on basic chemistry and physics.
Do you suppose that a legislature might make laws (which might be commonly, if imperfectly) enforced regarding the possession and use of guns and bullets?
Do you suppose that a person who manufactured and sold guns or ammunition might at some point find it helpful to be aware of those laws?
Note to the feebleminded: I have a lot of guns and bullets. Molon labe. I believe the Second Amendment protects an individual RKBA. I am not arguing that guns should be more regulated. This post is not about gun control.
This post is pointing out that governments attempt to, and with varying degrees of success, regulate items and processes which operate on basic physical or mathematical laws or processes which are themselves beyond the legislature's reach.
If that observation is insufficient, you might consider whether or not governments have attempted to regulate the growing and processing of certain plants, or of relatively simple chemical reactions/transformations that can be applied to ordinary chemical compounds. Those attempts have obviously been less than wholly successful; but they have certainly had a significant impact on people interested in those plants and those chemicals, to the extent that many people who would like to use those things do not, and others incur significant costs adapting their operations to the the risk of (imperfect) intervention.
