No, if they wanted to deny the case on its merits they could have done so. They chose to deny standing instead, probably to avoid pissing a lot of people off. They did not say it was impossible to grant relief, they said they would not grant relief. What this means is open to interpretation, for example, they could rule that the elections were conducted in violation of the Elections Clause but that it is up to the state legislatures to decide which electors to appoint, which would actually be a good outcome for the Trump campaign. In order to say whether the case is good or not you would have to point to something specific that makes it legally weak. E.g. controlling precedent. Standing has no bearing on the merits of the case, so everyone using standing as an argument is not making a real argument but is just playing a shell game.
