I think it must be something about the profession that causes the unease… I started a FSBO newspaper a while back in a town my husband and I lived in briefly. We hadnt owned our home long and all the profit of the sale would have gone straight to a realtor. We were a young new couple (with baby) and I wanted to preserve our meager profits. I thought, ‘If only there were an auto-trader-type for homes.’ (Turns out there were similar businesses elsewhere in the country, just not where we were. This was pre-internet). So, I called all the other FSBO in the regular newspaper, went and took photos, and had my first paper out in 30 days. The local realtors went bananas!!!!!! Phone calls, rude looks at the grocery stores… Luckily I was VERY young, and they really couldnt do too much damage to me personally. I let it roll off (and i was moving anyway). Still, life lesson learned… dont mess with the realtors!
Incidentally i sold my house immediately, and also the business soon after!!! it is still in operation today, a more than a decade later.
