>The weakness is the hole and tiny amount of surface area it has to grip

Maybe if they were pocket holes or just end grain screws yes. The reason metal brackets are the strongest is not all about the screws but the fact they are able to effectively change the leverage (sometimes even increasing the surface area) of any force being applied to the joint itself at the same time. They do so by acting not just as connectors but as braces as well. The superior strength and isotropic nature of metals allows them to essentially act as pic related as well as a joint.
