Access denied or access required implies there are barriers: closed doors, steps, text, voice, tools that require ten finger dexterity and so on. Open, in a spiritual sense, requires us all to be part of an omnipresent ether.
We are each unique, indivual and alone. Anything else is a label, catergory, sub-category or grouping defined by others to simplify their or our collective perspective with every kind of bias attached.
The level playing field can never be level enough. A new and better metaphor is required if it is to imply that everyone has an equal and fair chance.
