In all countries around the world there currencies are all printed in paper which is called note though there maybe countries who still use coins till now. All around the world money can be misplaced maybe from your pocket, your hand or maybe your wallet may even get lost but still some people don't feel it when their money get lost because it's not that very high in exchange like in Nigeria where we have our highest currency which happens to be 1k and many other currencies like #500, #200, #100 and others most times we misplace this money and others pick it up with joy of having what you didn't work for but in this recent economy everybody has refused to lose money as usual ( laugh ).
What if the Bitcoin was in notes and with the same value as it has now, do you think anyone would misplace it or even walk with it on the street. Eventually you see a Bitcoin note will you return it to the owner. Let's be sincere and also see it as fun.
Bitcoin been in Note will defeat the idea behind Bitcoin to even start with, if you really understand the idea behind Bitcoin is sure such assumptions wouldn't even cross your mind, I'm not trying to say any less of your idea but I'm only trying to be logical as to why your assumptions seem not to be adding up, unlike other regular currencies which are also regarded as Fiat, they are asr only there for the exchange of goods and services having been valued in their local denomination but with Bitcoin the idea it totally different as it goes way beyond just for the purpose of payment a d valuing for a certain amount of Goods and service but with Bitcoin a store of value which is independent of external control can be achieved.
There are much more to Bitcoin which I can exhaust responding to this thread and that's why I would just say the idea behind Bitcoin is just so much that it just can't be reduced to mare notes and be exchanged commonly amongst individuals on the streets of any city.
