Not by everybody.
"An inference from the doctrine that a single state has a right to secede at will from the rest, is that the rest would have an equal right to secede from it; in other words, to turn it, against its will, out of its union with them. Such a doctrine would not, till of late, have been palatable anywhere, on nowhere less so than where it is not most contended for." - James Madison, 1832
"My opinion is, that a reservation of a right to withdraw...is a conditional ratification; that it does not make New York a member of the Union, and consequently that she could not be received on that plan. Compacts must be reciprocal - this principle would not in such a case be preserved. The Constitution requires an adoption in toto and forever. It has been so adopted by the other States. An adoption for a limited time would be as defective as an adoption of some articles only. In short, any condition whatever must vitiate the ratification...The idea of reserving a right to withdraw was started in Richmond, and considered as a conditional ratification which was itself abandoned as worse than a rejection." - James Madison, 1788
"But the ability and the motives disclosed in the Essays induce me to say in compliance with the wish expressed, that I do not consider the proceedings of Virginia in 98-99 as countenancing the doctrine that a state may at will secede from its Constitutional compact with the other States. A rightful secession requires the consent of the others, or an abuse of the compact, absolving the seceding party from the obligations imposed by it." - James Madison, 1832
Agreed.
The word I used, commonly concedes that.
And as I said about Californias secession, that they should take their share of the Federal debt with them. This is part of what Madison said about A rightful secession requires the consent of the others, or an abuse of the compact, absolving the seceding party from the obligations imposed by it."
I will say that the other states would have no right to impose onerous and unfair conditions of the exit of the seceding state so as to preclude its exit.
