We should not be so dependent on one person that if they are compromised because of deepfakes everything collapses. People need to be taught to have more patience and to question questionable things like that. Give the benefit of the doubt.
And realize that penalizing regular people's access to something good or necessary because of bad actors won't hurt the bad actors. Nothing in this legislation provides teeth against what you're describing. There are also other strategies that explicitly do not involve banning access.
Rather, encourage and leverage access. When everyone has deepfaking capabilities just because of fun filters in snapchat, it's encoded into the social contract from a young age not to abuse that except in jest. There are paper and log trails all over the place when these services run. A deepfake being created means a deepfake is detectable.
