to match the $3.24 Billion spent on lobbying in 2014

Who says every dollar needs to be matched? If a corporation lobbies for rubber subsidies, no one will give a shit. If a corporation lobbies to make it a criminal offence to mention their brand online without a license, that crosses into free speech which might be worth a dollar or twenty to those who find that kind of thing important.

It's not the least bit realistic

You don't necessarily need to spend more than the corporations, you just need to make it lucrative to stand up for the good guy. If you can have $1m to be evil or $900k to be good, the $100k lost is more than made up for by the advocacy of those you served. It's free advertising.
