Why do you want a Lambo?
To me this seems contrary to the ideals that would support the liberation of IP. Why should we be wasting resources on such things?
You'd probably be able to get any item you liked with a Lambo TM (or are we keeping some form of trademark laws? please?) and certainly be able to buy some sort of Ford/Toyota/Kia with a Lambo shell. But it will definitely be a knock-off.
Lamborghinis will still be expensive not because of scarcity but because they're a huge waste of money and so in practise few people really want to spend the money on them.
If you wanted a Volvo instead I think you have a chance but you'll probably find it extremely hard to get one that lasts more than a few months, is safe. It will probably be even harder to get parts that are actually worth fitting.
If you wanted an iPad then I think you stand a chance and it might actually be half decent, Chinese factories are already making ripoffs of such things after all. Apple would have to own the supply chain outright otherwise the manufacturer will undercut them (sell at lower price exact same product) and Apple would be left with the R&D and design bills.
Producing "information stuff" is difficult, but copying it is extremely easy.
You can pay a team of 100 guys to work for a year creating a program, a movie, or whatever, and then have it copied around the internet in a few hours, for free. Leaving you zero income, and a large loss on your sunk costs.
That's why IP exists. There is ample scope for arguing about whether the present rules and regulations are ideal (I don't think so), but the idea behind the system makes sense for many situations.
