Well, I don't know how your contract and contingencies read so it is hard to say, but if I had to guess it would be due to the following.
1. The MLS or State contract as you put it, has probably been vetted by board of realtor attorneys and offers protections for both the buyer and seller and conforms to state and federal law.
2. There are likely a number of contingencies offered in the MLS contract, financing contingency, appraisal contingency and inspection contingencies. If you are adding many extra contingencies this can make the offer not as appealing.
3. I would assume your contract favors you, which is understandable, but the agent has a duty to protect the interest of the seller, not you.
4. The agent would be signing your contract, and obligating themselves and their buyer to a contract and are not attorneys, they may need to verify that the items in your contract and ensure things are in the contract that may need to be due to their duty as agents.
5. Inspection time frames - basically they and the seller are trying to sell the house, the time frame is short to speed the process up, if you aren't going to buy, they can quickly get the house back on the market instead of leaving it tied up for an extended time period for inspections.
Again, without seeing it, that is just my guess.
