The point about lawyers is just that Harry sees the wizard world as rather quaint and old-fashioned; Lucius is a big frog in a very tiny pond. Let the Masquerade be broken in any serious way, and within a year or two Muggle Britain will have produced anti-curse body armour (possibly made of tinfoil) and guns that will reliably break a wizard's shields. In other words, it's not just wizard lawyers that are cute; wizard soldiers are also fundamentally non-serious. This may not be actually true, but I think it is what Harry believes.
By the way, in the Rowling-verse, the Prime Minister is supposed to know about the Ministry of Magic; he's the one official point of contact between Muggles and wizards. I wonder if that's also true in the canonical version?
It's not body armor and such that matters. It's control. Wizards have mind magic. They can alter memories and control people. That would let them act through agents who already possess muggle resources, and who already understand (and can explain whenever necessary) the strengths of the muggle world.
At the end of the day, if wizards seriously get interested in the muggle world, and muggles in the wizard world (not that they should get the chance, if the Malfoys are smart), and both learn about each others' strengths, wizards will still be the ones with the edge.
