You don’t understand what it means to be a Federal Government.
When colonies or territories or independent countries like Texas ask to join the Union they do so acknowledging the supremacy of the Union.
The other members vote them in and only the other members can vote them out.
Otherwise a Federal Government like ours is nothing. What if Puerto Rico, after we’ve spent billions on them, votes to become a state. Then after we’ve financed all the modernizations they need, what if they say “Adios!” and take the money and run?

You don’t understand. The states were recognize as sovereign in the 1783 Treaty of Paris. They were not about to give up that hard won sovereignty just 8 years later. Had anybody at the time stated that the states could never leave or had that been a term in the constitution, not one state would have ratified it. 3 states including the two biggest and most important ones expressly reserved the right to unilaterally secede just as they had done from the British Empire. Every state understood itself to have that right.
