If it never affects you, then it is not a problem. Just being careful and observant one can avoid most, if not all, entanglement.
The problem is when one gets tangled one has to know how to not make it worse and have the tools, knowledge, skill, and ability to cut themselves free or disentangle themselves. The first time is the worse. Buddy diving can be an advantage, if this happens.
I did get caught in an illegal longline for rockfish while solo diving off the coast, it was poor viz and my wetsuit was hooked in several places and the line was caught in kelp before I realized I was snagged. It took a while to cut myself free without much further entanglement, the hooks I took out back on the beach. Without prior experience it could have been much worse. I started carrying a line cutter, as well as my BFK, after that.
I was taught back when diving was dangerous, and I contend that it still can be when things go badly.
