Specifically regarding firearms and self defense in general. Its a human right to be able to defend one's self and your property. With that in mind I've heard the advice from a bitcoiner in the ammunition industry that the single most important thing gun owners can do is join your local gun / sport club. Many are small family operated places that need to be able to keep up their property taxes. Building a new range is much harder to do that keeping one active. This goes double for states like California and New York.

Even if you don't use the services very often join your local range / club. We are winning but don't be complacent. There is strength in numbers and while you might have land for your training activities new gun owners likely do not. Building an ecosystem here makes sense as it does with bitcoin.
