There is a tangible difference between cutting off utility infrastructure and the fallout from shutting down oil refineries. Sabotaging a substation or power plant, blocking vital thorofares, shutting down water plants, etc will cause direct deaths and fall more in line with an attack on the population than a protest. That is what certain countries are doing to their neighbors and we rightly condemn that even in war.

Causing a drop in available fuel through refinery or pipeline embargo or sabotage would at worst cause rationing and prioritization to emergency services. This will of course cause damage to those that rely on transportation, but allows the ability to plan for/around that infrastructure disruption does not.

Blocking roads is the least impactful infrastructure disruption obviously, but disruption of fire, police, and other emergency services is still a more direct impact than what would amount to the 70s oil embargo.

When we get into acceptable losses, it can sound like the "left's" equivalent to gun rights. I am not saying these are the same, or of the same magnitudes, just that the argument is made for how many gun deaths are acceptable to retain fundamental liberties. Both are probably important discussions to have, but there will be people who is answered to both will be zero or who don't even want to engage with such a topic.
