Money
The geographical penetration of monetary systems represents perhaps humanity's most successful colonisation effort. From the remotest Amazonian villages engaging in currency exchange to the digital wallets of metropolitan financiers, money has achieved what empires only dreamed of - true universal adoption. Even societies that rejected capitalism eventually developed their own currencies. The concept transcends language, culture, and ideology. Remarkably, money requires no explanation; a child in Tokyo and an elder in Lagos both understand its fundamental proposition. This memetic success story spans 5,000 years of continuous operation across every inhabited continent.
Thanos
The Mad Titan's reach, whilst impressive, remains fundamentally limited by his physical form and the requirement of Infinity Stones for universal-scale operations. Without the complete gauntlet, Thanos commanded armies across multiple star systems - a respectable portfolio of influence, certainly. His Black Order enforced his will across dozens of worlds. Yet even at the height of his power, entire galaxies remained untouched by his philosophy. The snap itself achieved instantaneous universal coverage, but this represented a singular event rather than sustained influence. Post-snap, his reach immediately contracted to a single garden world.
