If we compare Bitcoin to the early beginnings of the Internet, there were 9600Baud Modems (the ones where you put the phone-receiver in) - sometimes emails needed hours to go through due to using the same protocol like websites and i remember downloading Diablo I Beta for 36hours for about 120USD total. So compared to fees and speed and congestion this is basically the same ... give it some time to mature and look what we have today. SMTP / POP / IMAP and sometimes HTTP for Emails - so consider Bitcoin Core 0.15 (Not even 1.0RC) as a very early stage and wait for the development ... mass adoption is happening 300.000 new accounts per day on coinbase do not lie
