Agreed. I've never seen any impact differences from having tape over my barrel. Shots out to 600 have been spot on. After carrying my rifle in my Eberlestock for a while, I began to notice that dirt and sticks and grim that accumulated in my rifle scabbard was being ground up by the end of the barrel and I could see dust and bits of crap in the end of the bore. I figured tape couldn't be worse than the damage to the crown and the subsequent 'firelapping' that was going to take place as soon as I touched it off.
We all fall, we all inadvertently stick our barrels into brush get snow in them, rain in them, dirt in them, etc. which then leaves us with the options of cleaning when we get back to camp and then shooting again if we prefer fouled bores, or packiing filthy or clean barrels out the next day. Much snow or rain in a carbon steel barrel will cause it to rust, same for stainless but it takes more time.
If you're worried about impact changes at long range you can remove the tape, I always double over the end of the tape so that I can pull it off easily for that "really long shot" where I have time. But I'm sure that my bore is kept in better shape, less work is required, and far fewer worries with some electrical tape over the end.
