Space concerns: fifty-odd acres isn't really that much. If you look at it as a percentage of a country it's almost nothing.

Obvious to Raiders: only in the sense that it looks like it would make a good base for anyone. Light from windows, smoke from fires, noise from everyday life, crops in the ground, all these would be signs for Raiders from any BOL. You can't really hide your presence completely.

Man hours to construct: that's why it will be constructed pre-Z. The luxury of time on a project like this is what makes it possible. doing this post-Z simply could not happen.

People needed to run it: Actually surprisingly few. Pre-Z it could be run by a single farming family (plenty of which still exist in the Caribbean and South American region) with access to a few modern tools. Post-Z then it will need everyone living there to work it, but that is part of the plan.

Overpopulation: A risk of any system. All I can say is that I have built in tolerances for extra headcount, and I do expect births and deaths from those inside. However, over the period of a decade I don't see the numbers fluctuating by more than 25%. 65 people of an average distribution means 13 would be children and 11 would be 65 or over (Western averages, not global). So 43 people of breeding age. 21 couples. One in seven couples has fertility issues, whilst those over 40 would be unlikely to have children without medical assistance. Again, standard distribution would mean that 9 couples have children. Average 2.4 per couple, (21.6) 22 births.

But the old people at the beginning have aged 10 years. And without cancer drugs and all the other healthcare wonders, it's almost certain that they won't last a decade. So 11 deaths. Total of 11 extra mouths to feed. Well within the tolerances.

Contradictions? Can you expand on this?

A patrol/scout scenario should have as little a force as possible. The larger the force the more likely being observed and intersepted. Or worse ambushed. Now a raid would require the personel you need for the mission. A medic trained scout would be a good idea.
The doc should stay at BOL because he would almost have zero stealth skills. And if the only trained doctor not worth the risk(here)
But again the idea is to be small, fast, quiet, and the best scout/fighters to offset the lack of numbers.
If you send a large force with people for almost everything that might happen you will quickly have a large, slow, and noisy group of walking targets.

"Sure, all you have to do is donate $100,000 to my fictional cult."

Considering this is a fictional cult, here's a fictional $100,000, now give me my Snoopy RPG.

"Pedro, have you thought about luxury crops?

Tobacco, saffron, indigo, etc.?"

In general, yes.

Tobacco was deemed unsuitable for a small farm because of it's toxicity to plants and animals.

Saffron is on the herbs list. (Thanks to Eostre)

Indigo grows wild in most of the Caribbean. It has medicinal use as a painkiller and anti-inflammatory. It isn't on the list, but should be. I'll add it now.

The point of the tiers is to funnel the attackers through narrower channels. The last wall is 300 feet long before they breach tier 6. If a huge force was sighted, pulling all the way back would give us time to pick off the other attackers.

The tiers don't inherently protect the crops, they protect The Castle. A single defensive line would mean that any breach risks losing everything. But with the design here, a smaller force can progressively thin out a larger one to even the odds. All but the most agressive attacks would slow and stall as they conquer successive walls.

Aruba, Bonaire and Curacao were chosen from a long list of possibilities specifically because they avoid the worst of the hurricanes. The worst reports list the following: loss of tradewinds result in an INCREASE in temperature. Rougher seas. Strong winds (6 on the Beaufort scale) and dark clouds, with maybe some rain.

I live in England. We call that the fucking SUMMER.
