Specifically, collecting a reasonable amount of taxes is key to the function of governments as they're set up.
It would be unethical to sell somebody a car that secretly has no motor, but ethics isn't the only reason cars need motors.
If taxes were about financing the government there would just be one tax called the-cost-of-government-tax and that's it. There would be no need to tax everything you do, and at different rates and on some days but not others, but when the moon is full on tuesday you pay double except if you lived on 72nd street during 2008...
Taxes are about control, about influence, and about corruption. The loopholes are there becasue someone put them there, they are not hidden. The tax-code is so complex because someone made it that complex, someone doesn't want it to be easy.
No they didn’t. Most governments are mostly funded by taxes.
(The rest of your post doesn’t support this thesis, but instead the thesis that funding government. operations isn’t the exclusive purpose of taxes, which I don’t think anyone would dispute, and which is orthogonal to whether governments are mainly funded by taxes.)
Last year, the US collected $3.42 trillion in taxes, but spent $6.55 trillion for a record deficit of $3.13 trillion. This year is projected to break that record.

Since you mentioned the debt ceiling, that’s another concept that doesn’t make any sense (except as yet another thing more politics can be piled on to). It’s like first the congress votes on the size of the budget, and then separately on the size of the door that it has to fit through.
No, most countries finance themselves primarily by taxes; they typically also use debt financing, especially (in relative terms) countercyclically in economic downturns.

So, even the best single example you could come up with is...financed primarily by taxes, even in the one year you tried to pull as a counterexample?
