The point is to disavow the GP of the notion that the UK state is trying to do anything but generate more income for itself by illustrating some of the more recent utterly disgusting decisions the UK state, as an organization, made.
So:
Fairness - Nope
Fixing competition - Nope
Altering the market - No
Incentivizing European offerings - Nope
None of this is a goal. Another example linked to is that the UK state is an organization that has been known to use violence to kidnap child abuse victims, and lock them in with other sex offenders, then afterwards refuse so much as acknowledging that might have been a wrong decision, when the inevitable happens.
Such an organization, I'm sorry to say, can be reasonably assumed not to have the interests of you, or me, or anyone but itself, at heart. It's on the side of big companies and tax law is just driving a hard bargain. It is very much not about making their own job harder by doing such things as massively increasing the number of people they need to negotiate with (otherwise known as "competition").
But go ahead, down vote me, of course the state is the epitome of all that is good of the universe. I understand that if that were to be a flawed way of seeing things, social policies start to sound a lot less like they're helping, and much more like they're cynically designed to increase the abuse suffered by the "helped" people, and prevent them from finding actual help, get out of their situation, or find redress. This shows you a new way of thinking about social policies and why they're made. Anti-child abuse laws are about encouraging child trade (and with that, inevitably, abuse), and preventing at all costs any means those kids might want to prevent the state from harming them further, and above all, to eliminate any legal redress such children might have against the state, at the damage done by it's agents to them.
Of course, one can easily make the determination about these policies. Find a few homeless, find a few now grown adopted children, and find a few that look smart, and ... ask them.
We all know what view they will have. The irony is that usually people turn those opinions into "see ? We need more child care/job programs/homeless assistance/...". A method for preventing those very programs from inflicting future damage as was done on these people is never discussed.
