None of the quotes you’ve provided demonstrate that Omani rule over the Somali coast was direct or absolute. What they show is that Zanzibar maintained a commercial and administrative presence in some coastal towns but that presence was consistently contested, limited, and often dependent on internal Somali dynamics. Local factions (such as rival Imams or town elites) frequently invoked Zanzibar’s involvement to settle disputes, whether internal or against powerful inland forces like the Geledi or Bimaal.
This is precisely what made their control nominal: they were constantly subjected to boycotts, sanctions, and political pressure from the Somali interior.

Even Revoil, your own source, admits this when writing about Merka:
"Merka , which is in the Bimal territory, is always under siege because of the perpetual struggle between this tribe and Sultan Hamed Yousouf ad , as the Arabs do not have the slightest influence in the interior, it is to be feared that the trade of Meurka, once considerable, will be destroyed within a two or three years.

This directly illustrates how the Omanis had no meaningful influence beyond the coast and even their hold there was precarious due to pressure from Somali clans inland.
You also overlooked key evidence from the same historical period, such as this 1876 British parliamentary report, which describes how even Geledi-affiliated leaders were levying taxes on the governors and residents of Marka and Brava clearly undermining any idea of direct Omani sovereignty:
'Addormo, governed by Abobokur Yusuf , another brother, who , though nominally under the orders of the first-named Chief, levies black-mail on his own account and negotiates with the Governors of Marka and Brava direct."
''Abobokur Yusuf was accustomed to send a messengers to Brava for tribute, and he drew from thence about 2,000 dollars per annum"

As for the issue of Banyan monopolies: what you’re highlighting is more directly tied to British colonial economic expansion in the late 1800s, rather than Zanzibari dominance. Indian merchants, tied to the British East India Company, were displacing Somali merchants through predatory lending, property confiscations, and unfair trade practices.
Again, from the same 1876 source:
''and the whole coast peopled by the Somalis to be come even more unsafe than at present, and our prestige greatly suffer, and this just at the time when marka is beginning to be almost a colony of British-Indian merchants, so much so that even Hindoos talk of bringing their wives and families there.

Scott Reese and others have written more extensively on this. What you’re seeing is not an extension of Omani control, but early British economic colonization, using Indian merchant classes as a wedge to undermine Somali commercial autonomy.

This is not an example of Omani domination but of creeping British economic colonialism, which often exploited coastal merchant classes (like the Banyans) to muscle out Somali traders.
Regarding Kismayo this narrative needs to be corrected. The town simply did not exist until Somali migrants from the interior founded it themselves in 1869:

''In 1869 this town did not yet exist , but the in that year some Somali emigrants from the Upper Jubba Valley and especially the from the neighbourhoud of Bardera or Bal Tir , the chief market of the interior established themselves at this favourable point of the coast, and opened direct commercial relations with the Zanzibar. Later some members of the Mijurtin tribe (Majerteen) tribe, the most energetic traders on the whole seaboard also settled in the same place"

So the idea that Somalis were “chased out” of towns they themselves founded and built is historically inaccurate.
Even the garessa (Not quarters but forts) you mentioned were built primarily to protect foreign merchants from Somali resistance and attacks not to exclude Somalis from their own urban spaces.
