You're already modded down, but at the risk you're looking for a discussion, let me see if I can relate how I understand it, personally:
"Liberty" relates to "budget" under the terms of "small government". We can have fewer programs, at least at the Federal level, and that would in itself be good, but it would also cost less. That's not at all incoherent, even if it wasn't explained in detail. Less liberty will basically always mean more spending, because someone has to fund the enforcers, the tracking system, etc. There's just no way to implement a program like that for zero cost. A libertarian sees fewer programs as a win-win in this way.
"Budget" relates to "taxes" because the government should not have any other income. Taxes are one entire side of the balance sheet that makes up the budget. Ergo, a smaller and/or balanced budget would lead to fewer taxes demanded in the future.
Again, more wars means more tax needs. This point should, and I underscore should, be completely obvious to anyone, whether you agree with it or not.
There does exist a framework for running our government. Most of it us under glass at the National Archives Rotunda in DC, I think. Otherwise, I'm sure you can locate a copy online with relative ease.
Budget neutral is not filler. That's crucial, because the taxes are, again, the only income for this business entity that will be managing a large portion of the economy. Responsibility is paramount, because our children deserve better than 'pay for it somehow tomorrow'. At least they do if we do not wish the USA to follow in Rome's footsteps.
Abortion is not filler because these are public dollars being spent. If the constituency is not in favor of this type of expenditure, then it shouldn't probably occur. Unless there's some kind of opt-out provision that I'm unaware of...
The latter of your point is a fine position to take. My only rebuttal there would be that once/if the system is no longer broken, we will see no opportunity to remove this program. It is not a 'fix', it is a retrofit. If we're unhappy with it, due to the entitlement angle, we'll simply suffer under it forever - as we will with Medicare.
