Creating a clean identity from scratch is quite easy...

1) make up a name
2) apply for a taxpayer ID number for a business with that name
3) using the name and the taxpayer ID, open an online bank account and fund it
4) using the name and taxpayer ID, apply for a few credit cards...you will get at least one approved
5) run some money through the system by charging the cards and paying them off through the online bank account

...the above gets you some visibility in the system. Now head to LA and pay about $200-$300 for a state ID card with your fake name that will allow you travel or do other activities that require ID

It's all quite easy to do...and the roadblocks are few and easy to overcome...some of them just require paying abit of cash
