From people who deal with the trust and safety side of things, at a national scale of a few billion people, 10 people is definitely not enough.

What size of population are you considering for this hypothetical nation?

Which problems do you see that would require all of this, given that it is a nation platform where you are authenticated via your government ID?

And which nations are scaled to a few billion people?

And they all date? Every single one of them? The married couples? The children and the elderly?

Singapore's population is 6 million, about 1.7 million are aged between 16 and 40.

That's 1000 times smaller than your "few billion" scale, before you remove those already in partnerships or those who don't want to.
