Firstly, 'conduct the transaction in cash in person'. That sounds pretty accessible to me. You have cash, you press a button on your phone which shows the nearest person selling it, you go there and buy it from them. Can it get any more simple than handing over money in return for an item, like buying a coffee?

But secondly, there are various companies right now that offer quick and easy purchase. Try Circle for example, you can instantly buy bitcoin there with a bank transfer, even though the transfer takes a day you get your bitcoin, and at 0% fees, too. If you compare that to just 3 years ago when your only option was shady and risky as hell, or hell, even a year ago, it's rapidly improving.

For example here in the Netherlands I could buy bitcoin between now and one minute from now, safely and legally and I'd receive my bitcoin right away, using just my phone and not leaving my seat or registering for any account. (Bitonic)

In Canada I can pay by debit, called an Interac eTransfer. Check out Vault of Satoshi. The funds are allocated in about an hour.
