feel free to put resistance where you expect them for realistic

Very impressive but it's not because of no resistance, it's because the current source is modeled "perfect" without any supply voltage limit. And of course to maintain constant current through a cap you need to charge it up with more and more voltage. So if you choose a very low cap value and a very high current the voltage will skyrocket of course.

Well technically it’s also because there’s zero ESR that’s why the voltage can be infinite

a constant ESR would cause a constant voltage as offset, nothing else. e.g. 1Ohm at 1MA would cause constant 1MegaVolt, which is irrelevant after a few seconds. So resistance as you say is not a problem at all for this unrealistic circuit
