ELI5: Why does acid+base make salt + water?

Ex. why can't HCl+NaOH remain where they were instead of dancing around and form the double displacement (H2O+NaCl), aren't their charge already stable to remain where they were?

HCl and NaOH are both strong electrolytes (meaning that they completely dissociate into ions when placed in water). This means that you don't have HCl or NaOH in solution. You have H^+, Cl^-, Na^+ and OH^-. 

When H^+ ions come into contact with OH^- ions, they form water. Since water is a very weak electrolyte (only about 1 molecule in 10 million will dissociate), it stays in its liquid form. All of the other possible combinations of ions (H and Cl, Na and OH, Na and Cl) will not form in appreciable amounts because of how soluble they are. At the end, your solution is left as H2O, Na^+ and Cl^-.
