What I have wanted for a very long time for America:

1. The government cannot ban any speech in advance of publication (eg verbally making the statement; or airing; or publishing etc).

2. If proven in Court that the statement maker: (a) knew the statement was false; (b) made the statement for the purpose of influencing public opinion regarding a law or government policy or election; or for the purpose of marketing a product for sale to the public; then the penalty upon conviction is...:

here is the secret sauce: super severe penalty such as: imprisonment without chance of parole or pardon for 10 years unless you are an elected official or candidate for office, in which event life in prison; or loss of 50% of your assets; or something similar

In other words, keep freedom of speech but if you are intentionally lying to the public for the purpose of impacting government affairs or the sale of a product - then you are going to suffer an incredibly punitive penalty.
