That point was, much more politely, made in the House today. Namely, how many more will really be ready if we delay until June 12?
More people will be ready. And they'll have coupons that they can use.
Some will never be ready, mostly because they just don't understand. Some simply aren't smart enough and some has been fed misinformation.
Stations have already applied for a 30 day "nightlight", which is permission to continue broadcasting in analog which will be used to tell people what happened and also for emergencies. So it won't "go dark" on the 17th.
I if were handling it, sometime in October I would have organized something where the analog stations would be nightlighted for 24-48 hours then turned back on again. Of course, D* would have accidentally nightlighted my FOX and NBC affiliates, as D* was still using the analog feeds for those stations at the time. (Actually, for FOX they still are!) But it would be a warning of what was to come and would be something people could understand and then react to.
The current bill is a mess, as some stations will switch anyway and some won't. But it's better than nothing.
