Where are my Investor-Friendly Real Estate Agents and Brokers? Maybe you can comment on the below and prove me wrong??

I am curious to uncover how all the rest of the investors (and agents and brokers) here feel about real estate agents and real estate agent fees in today's digital age where we have so much information that we can dig up on our owns from: county records, mortgage/liens, previous purchase prices, land values, tax histories, rent price history and the advent of online listing services and other sources of real estate wholesale listings and auction agencies online. Do we NEED agents?? It feels we can market deals ourselves and find deals ourselves. Real Estate agents taking 3% of my home's value during sale without doing any of the work to maintain the house or in any way contribute to the value of my property does not sit well with me. On the flip side it works against you too - 3% of the home's sale goes to the buyer's agent - but you are paying for that too when you make the purchase! I think they do not have enough incentive to save you money, find a deal that is going to work for you, and the juice is not worth the squeeze. I would rather negotiate my own deal with the owner or the owner's agent when I buy and would rather pay the MLS listing service and get the title agency to provide the paperwork for a FSBO listing. Maybe I am in the wrong and I am losing money with a realtor, maybe you all can call me out and tell me I have a myopic, "scarcity" mindset.
