I'm in general against mass surveillance (on privacy and potential for abuse grounds), but that a measure is not perfect and can be worked around with some skill and motivation is not a good argument against it on its own. It is possible for an imperfect system to increase minimum level of motivation sufficiently to reduce incidence significantly. Same as in cyber security -- that you have no chance against a state level actor doesn't mean you shouldn't use good passwords and 2fa on your accounts. Because for some criminals effort becomes just not worth potential gain.
