Curious about EU import taxes

So I searched, 'EU import taxes'.  I found pages and pages of regulations.  But I also found the neat little duty calculator from Pitney-Bowes.  The company is selling digital shipping tools, they have transformed themselves from a mechanical postage meter company.

But I digress.  The point is we have hardware brains that can graph the rule set, and you convolve a query over the graph.  On a basic Turing sense, that is what Pitney is doing with duty calculator.  The rule set from the EU easily transformed into a semantic graph over which any rule combination can be discovered.

So, the point is, transaction costs due to cross border trade should drop nearly to zero.  Taxes remain, but everything becomes Coasian efficient, this solution will be as good as any other.  

My suggestion to the Brits is simple: Get the software geeks working on dropping trade transaction costs nearly to zero.  Then any Brit exporter can immediately determine the suggested gain for any cross border transaction.  The receiving country can easily match their duty income to any dead weight trade losses they accept.  No transaction costs, anywhere, every trade becomes a simple Coasian adjustment.
