You can't have a country that doesn't have conscription in time of war. For example if Russia were to attack which is unlikely but plausible. I don't like conscription at all and it's necessary but still an evil.
It is not necessary, because the state has a legitimate right to taxation. Every non-military person in the country can be taxed down to the poverty level to pay volunteer troops. This is morally superior to enslaving people.
Some countries don’t see sex as a criteria for conscription: good job Norway, Sweden, Denmark and the Netherlands.
