I know the difference, I'm just saying that I don't believe it's fair.
Either remove the limitation of liabilities, or forbid directorship of another company until all liabilities from all liquidated previous companies were settled. It'd stop companies which run up debts, or operate unprofitably, knowing they can just escape at any time leaving their debt behind. A good example of this is a double glazing company here in East London which I won't name. The same group of people have been running the operation for about 15 years now, yet they've been through several companies, every few years ditching their debts, both private and tax.
And it's not a barrier to commerce, it's paying what you owe.
