Even if you believee the claims, the EU - especially Germany - is heavily involved in economic development of the country. Kosovo is very keen to improve their EU integration. So, you might be able to side-step Kosovar authorities, but gain the attention of the EU and you're not going to be protected by incompetance or bribery of local law enforcement.
As an aside - it's a great place to visit. Friendly, safe, cheap (for now), good weather. Looking forward to returning one day.
