The difference is that one inures to state governments rather than the federal government. The concern at the time was that the federal government would take guns away from people in order to neuter the States' power to defend itself. The States themselves free to do what they wanted to regulate their citizens and militias.
I wonder to whatr extent BTC could be seen as an investment in a corporatist future where nationstates are less influential than the fictitious entities they have spawned.
I don't disagree but wonder whether the fact that it doesn't have a phyiscal property would militate in its favor over gold. I recently read a story about how a Saudi prince was having a few tonnes of gold driven to a neighboring country every day in order to avoid trade restrictions. Seems like it would be a lot easier and safer to just click a button on his computer. That said I could imagine it easily cutting the other way and saying that golds tangible properties are an advantage. This is a fascinating subject!
It also just involved a click of a button. Nonetheless it was uncovered.
Too often would be cypher-anarchists forget about rubber hose cryptoanaysis. And unlike gold, bitcoin are fundamentally non-fungible and traceable.
The biggest advantage gold has over bitcoin is 5000 plus years of history as a store of value. The biggest advantage bitcoin has over gold is its immateriality. Personally I think the former outweighs the latter (no put intended).
