These are two separate issues. The court itself isn't behaving conservatively as some thought it would. Its behaving unpredictably which means the fringes of each side of the political spectrum will be unhappy with it.
Meaningless statement. The court never behaves as "some" thought it would.
However, the court is behaving exactly like many here predicted it would - rubberstamping conservative business interests and all the most high profile and long-lasting conservative political interests.
The conservative movement as a whole, is on the rocks in the US. Trump has completely dismantled the traditional three core characteristics of American conservatism (fiscal, social, and defense) and converted it into a full on culture war cult of personality that rejects science and enables anti-government violence. That is not a long term sustainable model for any political party - especially not one with aging, homogenous demographics who aren't being replenished by younger adherents. This is why Rs have taken to gerrymandering, voter suppression, court packing, immigration restrictions, and various other policies - because they know they can't win without cheating. This is, again, not a sustainable model for any major political party in a democratic system. So unless the US is headed to full on authoritarianism, the conservative movement is going to gradually run out of sufficient voters to continue winning elections.
That naive optimism is charming but I fail to see any evidence that really supports that due to the facts I listed in the first post which you ignored to focus solely on a handful (out of hundreds) of SCOTUS decisions while ignoring all the pro-business SCOTUS decisions and important political decisions like this one on abortion.
Also, I wouldn't call controlling 27 governorships, 30 state legislatures, and being able to pass more restrictive abortion laws than any time in the last 50 years "on the rocks" either. It takes a lot of mental gymnastics to conclude that conservatives pushing laws at state level and getting away with it as proof they are "on the rocks". A more reasonable interpretation of all these laws being passed is that after 45 years of conservative infrastructure building (from legal to lobbying to media) conservatives are able to pass these laws and get away with it when 10, 20, 30 years ago they would not have been able to get away with it.
Oh and another angle:
The Democrats controlling Pres, House, and Senate can't/won't reform marijuana laws despite the War on Drugs being a massive failure.
The Democrats controlling Pres, House, and Senate can't/won't pass actual Federals to protect election and reduce disenfranchisement being pushed by state-level GOP control.
The Democrats controlling Pres, House, and Senate can't/won't pass laws strengthening the social welfare system and reverse 40 years of decline.
The Democrats controlling Pres, House, and Senate can't/won't pass laws protecting things like affirmative action, which have proven positive benefits in social mobility.
etc
So it doesn't really look like the conservatives are on the rocks. It looks like they've sufficiently infiltrated both parties through money in politics that they aren't solely reliant on the GOP.
