1) Even if you are correct about eg, metadata, they are also snooping your internet requests, emails, etc, simply because they pass through infrastructure not belonging to you.

Do you think the Founders would have said "if you send a message via Pony Express, you authorize the government to read it"?

2) "If I write down every time my neighbor enters and leaves his house, that's mine, not his." True, but one person writing down what one other person does is hardly scalable or powerful. Computers recording everything everybody does creates much larger potential for analysis and abuse. We don't know what the Founders would have said about this, but I oppose it on the grounds that the risks for tyranny are enormous.
