It's all reasonable stuff except maybe:

People’s names are all mapped in Unicode code points.

I don't see how you could avoid this this in software that needs to ask the user their name.

I think it's definitely a good idea to avoid using names wherever possible, and definitely don't try to do anything clever with them.

When necessary, software can just be clear:

• "in unicode, what should I call you?"
• "in unicode, who is making this credit card transaction?'
