I hear what you're saying, but please don't say that. The alternative is to just accept unchecked capitalism destroying our environment. So no, protesting is not futile and counter-productive. It's absolutely necessary to ensure that people remember what we're trying to change, while we change it.
Alternatives are suggested but they are largely ignored, postponed to the next legislation, criticized (with no scientific evidence) and finally hijacked by fake environmentalist who are just creating disinformation for their own interest/agenda
