I think OP didn't place their write up well for us to have an idea of the access they are talking about because when we talk about accessing bitcoin in a real definition, we are also talking about owning it which most of us know it is very easy to access bitcoin as regards to my explanation of what access means. I just feel that OP want to talk about the technical aspect of bitcoin that is why they talked about professional developers, i mean what has professional developers has to do with having access to bitcoin. So, yeah if they are talking about the technicality of bitcoin, they may be right because most people who are into bitcoin don't have much knowledge about the technical aspect of bitcoin.
If you take your time to learn about bitcoin you will find out that bitcoin is not actually difficult to understand. Moreover, you can't just jump into conclusion when you Haven't make an attempt to learn.
It is not just about learning about bitcoin, what you want to learn will determine if you will find it easy or difficult to understand.
