year 2050:
some if's and assumptions:
*99.9% of population has access to electricity and internet;
* robots almost ready to do all the dirtiest and manual work for humans;
*humans do mostly intellectual work, craft, art, etc.; they still can do manual and dirty work though, but only if they want to;
*energy is clean, unlimited and practically free;
Who would need bitcoin or any other kind of money in a world like this? It looks like people would have everything they need to live confortably, without even being necessary to work in order to survive and thrive. Since most human's necessities would be supplied freely, financial trades become near to useless. If it really happens someday the last of your worries will be bitcoin and this extreme equality mania.
