The whole "if you respec it equates to long rest for your spell slots" is a weird "exploit" to complain about, because simply pushing the rest button is an EASIER and quicker way to sidestep the process and obtain the same result.
It's like complaining that a billionaire with infinite credit can easily obtain borrowed money from another source. I mean, yeah, life is unfair, but in the end "infinite + something" remains functionally the same as infinite.
