While the huggy feels are nice and all - if unsurprising given the trio already have what's effectively an informal engagement - this plot arc is
complete fucking nonsense srsly.
1) Land ownership was Kind Of A Big Deal in any premodern society (and no small matter in modern ones for that matter), doubly so in urban areas, and subject to both quite considerable attention on part of whatever authorities exist in the context and serious litigation in case of disputes. Not to mention that often enough it wasn't readily tradeable in the first place - it becoming so was a pretty major watershed in economic history - and there were routinely even more restrictions on the sale of lands used for religious purposes. Some random goons sure as shit couldn't try to seize some primo urban real estate by blatantly dubious means and actually expect it to stick, as opposed to having the authorities (represented by whatever armed force they keep on payroll to enforce peace) come down on them like the proverbial ton of bricks.
2) Same generally went for loans and the like which were often also subject to
religious opprobrium to boot - notably IRL both Christianity and Islam took issue with usury, and Medieval theologicians spent remarkable amount of time and ink on the concept of "just price" (which actually had some majorly beneficial effects in the long run but that's a topic for another day). And some random goons sure as shit didn't get away with strong-arming deeds off the wealthy; that lot could not only *very* readily appeal to the legal authorities (often enough consisting of members of the same class) but also tended to have quite enough hale & hearty household staff to unceremoniously evict such wannabe toughs into the gutter (rulers routinely had to impose strict legal limits on the sizes of household guards to prevent the creation of veritable private armies). While the "middle class" types were pretty universally organised into guilds and associations and whatnots that could and did readily pool their resources to deal with trouble - and in many societies were themselves armed to the teeth, forming the core of urban defense forces.
3) Religious organisations and buildings were if anything an even BIGGER deal, being important civic institutions of immediate relevance to most people in eras when effectively 100% of the population took the supernatural extremely seriously. You didn't fuck with them unless you wanted approximately the entire community pissed off at you - *kings* routinely had to tread carefully around them, and there's kind of a reason that for all their militant atheism the Soviet Bolsheviks (and later their assorted client states) were obliged to let the churches and mosques stick around.
Also, as vital civic institutions they were as a matter of course funded by the secular authorities and/or themselves directly owned outright substantial lands and other stable sources of revenue (plus were pretty universally exempt from taxes), much of it donated by pious rulers and private individuals. This substantial independent wealth not only secured their institutional continuity but also meant they pretty much never had any reason to take on loans - on the contrary they commonly enough had enough to spare that people, up to and including monarchs, borrowed money from
them. There's a reason temples were invariably at the cutting edge of administrative bureaucracy to the point it wasn't unusual for them to be roped into training scribes for the secular rulers - this was the origin of European universities in the Middle Ages and
clerk is derived from
cleric, for one example. And among the more prolific written sources surviving from the ancient civilisations of the Fertile Crescent are... economic records jotted down by temple scribes. (Indeed the genealogy of the very alphabet we're using here ultimately traces back to the ancient Middle Eastern cuneiform which initially evolved specifically for administrative record-keeping.)
4) The business plan of the wannabe Mafia here makes no bloody sense whatsoever, even leaving the above aside. Even assuming everything went to plan they'd then be the proud owners of a now acutely desacralised church building (a rather *solid* building one might add, ie. difficult and expensive to replace) and the land it's sitting on; how the Hell are they planning to turn a meaningful profit from it? They'd make money altogether more easily and safely by just holding on to the deeds and pocketing the repayments.
Unless of course their leaders could care less about the profit margins and are only interested in the building and/or land for some as yet unrevealed but no doubt nefarious reason...
@kaminomikan tbf these guys are just the footsoldier legbreakers doing the actual collecting. Looking like scary mofos tends to be advantageous in that sort of thing.
