Because other than Ireland, none of the colonies was an integral part of the UK the way Scotland is. So separation was a lot easier. Nor did most leave with massive budget deficits/debts, which Scotland has in spades. And Ireland struggled for decades after independence in 1922 with low growth, stagnant living standards, engrained poverty and high emigration, especially of its young. Indeed it was stuck on the economic doldrums til early 1980s. Nobody should deny Scotland can separate if it wants. But those who advocate it should be honest about the difficulties/hardships it will bring — instead of sprinkling it all with Nationalist fairy dust and dismissing critics who bring facts to the table as ‘charlatans’ and fake Scots. You should be confronting the real issues instead. But name-calling is an easier cop out.
