Each situation differs from the rest so each must be handled on the fly.
In the Eastern US a few years ago, we went looking for recent shells and such using Geological Survey data (usually outdated, of course) While staying at a (tick infested) state campground we were harshly informed that any fossils around were protected from collecting as they were a valuable natural resource. The ranger kind - of went on and on about that...sort - of a personal issue for him I suppose.
We got our specimens anyways, as that same park was grinding said fossils up and using them to pave the park roads. Some of the chunks were large and clean enough to procure. When I asked another ranger if it was OK to take a few pieces of the road bed for my sons fossil collection, he laughed loud and long before giving us the go - ahead to take home a few small pieces of "road gravel".
As for "honesty".....there is only
one correct answer to give when your wife asks if that new dress makes her butt look too big, and it may not have anything at all to do with the truth.
I give minimal, reassuring information to the property owner. I do not go out looking for fossils to sell. I do not know what I am going to find that collecting day - if anything at all - or how fine a specimen it may or may not be. I am in the moment and open - that is part of the adventure for me. It would be a tad premature for me to detail what the ultimate fate of any finds I may procure will be before I even find them. Thus, I am looking in an educated and experienced manner for what I believe may be found at a particular site. I stress that I am very careful and am a responsible adult. I always go with my wife, son and dog. If there is any hitch at all, I am gone to the next spot on my list - no problem.
I love road cuts! I have had numerous roadside conversations with various police officers due to this practice, all of them positive. This also must be done correctly with an eye towards safety and not making a mess. It is one thing to pick up a couple of decent specimens and quite another thing to open up a large scale impromptu roadside mining operation.
There are pros and cons to commercial exploitation of a site as well. When my family and I went mineral collecting in the Bancroft, Ontario area, we hit a place in the deep woods called the Bear Creek Digs. Calcite intrusions loaded with tourmaline, sheet mica and apatite are there, and 'glory holers' had been there exploiting the veins for commercial specimens. They took the arm - sized crystals of tourmaline and apatite, leaving the finger sized crystals in their waste piles. Since they worked the veins - which averaged maybe 6 feet wide at the surface - down to a depth of maybe 10 feet, there was a lot of rotted calcite containing neat stuff that they tossed on the scrap heaps. A great collecting day for us, lots of fine specimens - including some facet grade apatite - to take home, and only one black bear came through that day.

If it hadn't been for the commercial collectors hard work we wouldn't have found much at all that day.
