I know you are sarcastic, anyway you can do that at any time. For the price of a pizza you can have a share in a good wealth producing company. Prioritize otherwise, take ownership in some capital, and you can spend more later.
Right now the system is somewhat rigged, and the prudent saver is basically fucked. You have to lick ass of agents the non voluntary organization called government, now, if you want to play.
That is what we are going to change with bitcoin. We are not taking away capitalists and entrepreneurs, rich heirs (and playboys and bad music and a lot of other bad things). Only the rigging of the game.
Could be, but not because of the sound money (if you by gold standard mean sound money). Some people inherited money and land, which is ok (if you can't give your possessions away, you don't really own them), but if you follow the story back in history, there was robbery. Some king took the land by force, and gave it to some agent, maybe a general, as compensation for his assistance to kill for the king.
What we can have with sound money is +no bank bailouts (because there is no money to bail them out) +commercial debtor insurance only (same reason), +stable money value (or slightly increasing due to progress) +saving in money made possible +market based interest rate unfucking the current system of systemical misallocation of capital +smaller governments because they can only loan prudently and taxes will have to be less. It is rather a lot. Big changes ahead if this succeeds.
Going to sound money will not automatically reintroduce everything from the old days. You dont need slavery, and you don't have to go back to the productivity levels of yore.
