Realtors and the MLS are the gatekeepers to a sale generally. I think over time you'll find that realtors generally serve the interest of the commission, neither the buyer or the seller. They'll convince you it's a buyer's or seller's market and to pay asking or drop asking, whichever gets it to closing quickest. People would be much better off getting that % back in closing costs and still letting the title company to a majority of the work, lol.
Just like any business there are allies and rivalries, and politics involved internally as well. A realtor is going push a listed property, then a fellow brokerage's listing, a realtor friend's listing, a friend's listing, yours and FSBO offering buyer's agent commission last. They'll tell a buyer that FSBO house A is in a dangerous neighborhood but will tell that same buyer a listed home B around the corner is a great buy in a gentrifying neighborhood.
Having said that, you can travel the path of least resistance or not, it's up to you. If you're only looking at listed homes, I would drop your agent and just contact the seller's agent directly and deal through them.
In a few years I'll have enough liquidity to offer in-house financing and avoid realtors and appraisers all together. Utopia is real.
