Final answer:
Bota Singh's act of announcing a tax could be seen as a protest against oppressive governance, similar to historical examples of defiance detailed in the provided information, though Bota Singh's specific actions are not directly described.
Step-by-step explanation:
Although the specific historical figure Bota Singh is not directly described in the provided information, the context suggests a scenario of defiance against authoritative taxation that has parallels in the events mentioned. There are descriptions of individuals or groups who took action against what they perceived as unjust governing powers, particularly in relation to taxation and overbearing governance. A possible rationale for someone like Bota Singh to write to the Governor of Lahore and announce the tax he was levying on travelers could be an act of protest or rebellion against oppressive rule. This action would draw attention to the imposed burdens and potentially rally public support while directly challenging the authorities, analogous to the actions of Gil-Dong against the overbearing Governor or the colonialists' resistance against unfair taxation by the British.
