Your first question is "If all paper money were change into bitcoin"?
Do you think that it is possible the all paper money will change into bitcoin? It is impossible thinking and in real it will not happen, so forget it.
Secondly you are asking beggars can access bitcoin?
Actually i see normally Beggars have no access of fiat money that the reason they are beggars then you are talking about bitcoin, only educated people can access the bitcoin.
