Many people learn to sail in dinghies when they are kids and get plenty of experience sailing solo in regattas close to the shore. They may also crew on larger boats for friends/family members. Then, when they get a bit older, they buy a larger second hand boat which typically requires repairs. When parts break they replace and repair them alone rather than pay someone else to do it. In this way, they will accumulate experience over the years, they know how to deal with emergencies, predict the weather and they won't be fazed with the lack of sleep one typically has to deal with during a crossing.
For such a person, it wouldn't be very hard, especially with GPS, radar etc.
For a land-dweller to decide to do it one morning is a bad idea. Many things are not under your control, for example, containers often fall off large ships and float just under the surface, undetectable. It could make a hole in your boat. Some large ship might be on autopilot while the head of the watch is making tea. It could run into you while you're sleeping. You could go to bed in calm weather and get woken up with the boat on it's side in violent wind and all the sails up. You'd have to not panic, take the sails down, put up a storm jib, sort out the mess and sow the torn sails. If you haven't been in such a situation many times before in smaller boat and with other crew, it would be hard to deal with.
True, a 15 year old girl has sailed the Atlantic solo, how hard can it be? Personally, I first sailed a dinghy solo at around 7 or 8 years old. By the time she was 15, she could have accumulated 7 years experience in various vessels, including ocean crossings with family members. To put it into perspective.
