I see no evidence you have read the First Inaugural. In 1860 federal revenue came from land sales of Western land and the tariff. The federal government levied no tax upon the states.
And Lincoln did not threaten war. He explicitly stated that the federal government would not disturb any citizen in their homes or farms; that any violence must be first initiated by the South itself.
It is apparent you did not read or comprehend Lincoln's first inaugural. He said this...
In doing this there needs to be no bloodshed or violence, and there shall be none unless it be forced upon the national authority. The power confided to me will be used to hold, occupy, and possess the property and places belonging to the Government and to collect the duties and imposts; but beyond what may be necessary for these objects, there will be no invasion, no using of force against or among the people anywhere.
I have pointed this out to you in other threads...which apparently you failed to comprehend or refused to accept the truth.
He clearly states no war
UNLESS the seceding states fail to pay Uncle Sam.
The South clearly understood his meaning. He meant to kill them and destroy their property if they refused to pay him what he demanded. This is exactly what he did and for this, he committed treason and should have been impeached.
See the Morrill Tariff should you wish to inform yourself on this issue.
War is nearly ALWAYS:
1. A failure of leadership and;
2. Is promoted and executed by the power elite for nefarious reasons that usually include enriching the State and themselves.
The War of Northern Aggression (more aptly named The War of Lincoln's Aggression) was no exception.
