Pedro, your real wallet can be just as easily get stolen / lost and people get conned out of money every single day, it's no worse then shares in a company, you don't psychically see them either. And same goes for your basic bank account no electricity no atms/eftpos, no internet no banks, I doubt banks keep a paper record of everyone's account, it's all stored on servers / hdd's somewhere. I can understand why some people drain their bank accounts every week and use cash, or why old people stash $100's under the mattress. but even then paper / plastic money only has value if the economy is stable look at other countries money like Zimbabwe $1,000,000,000,000,000,000,000 notes and shit. TBH when shit hit's the fan it's gonna go back to the old days trading in gold and gems and spice/salt
