I'm probably going to get yelled at by others for saying this but here goes....
There is a lot of speculation on this thread an a good chunk of it is FUD. Kudos to the people who posted their local RE codes in relevant part to try to clear things up. The only thing I have to say about that is it's still worthwhile to seek competent counsel (which isn't a random guy posting on this thread) because other statutes might interact with those laws in ways you do not expect.
Take a Deep Breath
We would all have to know much more about the specific civil claims against the individuals who were busted for operating without a license to draw reasoned conclusions instead of emotional reactions. This includes the presence or absence of a real estate contract (or contracts,) the presence or absence of an earnest money deposits, the manner in which the contract / assets of the contract were marketed, and how quickly the individual who was prosecuted lawyered-up.
I suspect (but absent more facts) can't prove that these individuals who were busted (1) didn't get the properties properly under contract themselves, (2) advertised the property in a way that suggested they didn't have an interest in of the property. Those of you who have had your own deal marketed back to you in an email by some random guy know exactly what I'm driving at.
Get Actual Facts for Your Situation
Whoever said to call the RE board and describe your activities (I don't recall, this is getting to be a longer thread) I must respectfully suggest your advice is unwise. That is, in effect, like calling the police non-emergency line and asking if, hypothetically, the small amount of ahem... "herb yielding seed" you carry on your person is considered medicinal / non-criminal in your state. You'd better have glaucoma.
Rather, I respectfully suggest meeting with a competent RE attorney for an hour or two and describing your operation to him in detail. Ask around at your local REIA, someone will know a good RE attorney who works with investors and is competent to address your concerns. For heaven's sake keep his card in case something comes up. He may or may not advise you to get licensed, change your contracts, increase your EM deposit, modify your marketing approach, etc.
What to Do If the Local Law Is Unfriendly to Wholesaling
Your state laws are written by men, they're not carved into granite by the finger of God. They're not immutable--they can be changed.
Your easiest option MAY IN FACT be to get licensed at least in the short term. Even if you do, you may still want to see the law changed. How do you do that? Well queue flashback to High School civics class... contact your state rep and politely ask for it.
First things first, you need to be able to articulate your exact concern with the relevant statute and contact your state representative about it. For example, you might think that there needs to be a explicit exemption in the state RE code for persons with equitable interest (probably defined as some minimum dollar amount) which would clarify the status of your operation in a manner favorable to yourself and your fellow wholesalers. Or, you might ask for something else like the ability to do lease options in TX.
You need to be able to express why the current law is a problem, articulate a tailored solution that isn't likely to have unintended consequences, and explain the benefits of the proposed change to the legislator's constituency to your representative (more likely his intern.) Once you have a bill number and a draft, go back to your RE attorney and get his two cents, then get your buddies at the local REIA (and social media) to call and express support. Keep doing that until the law changes.
If MY MOM can successfully lobby to get a state law changed regarding adoption (yes, really) you can call your representative and personally lobby to have your state law changed in some small way that is more to your liking as well; if that is your wish.
What If That Fails?
Try again at a different time in the election cycle. You're unlikely to succeed on your first attempt. It helps a lot if you've done volunteer work for your representative in the past or have the same political affiliation. If neither is the case you'll probably have a more difficult time.
If you really can't get anywhere after considerable effort: there are 50 states and there is this thing called the 10th Amendment. The several states have a lot of leeway on internal matters like RE law. If you must, find state that has greater respect for personal property rights and the the right of individuals to freely contract with one other without undue state interference than the state you presently occupy. Once you've done that vote with your feet: pack your bags and move.
Obstacles exist to be overcome.
