There is no problem to make Military outpost at TL8 and to keep it at TL8 generation later.
But thats Military outpost and not preservation of full TL.

I could be wrong on minimum amount of people needed to preserve TL completely,though maybe someone here will dispute that :))

Edit:

What Im trying to say is that you need Structure to keep TL.Structure requires labour which requires big population due all segments that make our TL.

Maybe simplest example is just Medicine.How many different departments do big Hospital complexes have...so with few backups we are already at thousands of people and we just started.And if we lack even single department than our TL is already starting to slip due other Doctors not having same expertise as that department specialists.
