That would be the interpretation where someone actually reads the text of the Constitution instead of making up exceptions out of whole cloth.

> Does any organization/group advocate such an interpretation?

Yes, obviously. The Libertarian Party is one example:

>> … we oppose all attempts by government to abridge the freedom of speech and press, as well as government censorship in any form …[1]

>> We support full freedom of expression and oppose government censorship, regulation, or control of communications media and technology.[1]

Direct threats of harm are still actionable, of course. In that situation you aren't punishing the speaker for what they said but rather defending yourself in response to a reasonable expectation of imminent and irreversible harm. The speech is merely evidence of intent.

The issue is what is classified as free speech? Perjury for example might not seem like a free speech issue, but under the most extreme versions it must be allowed.

As such it’s common for groups to carve out what the want limited as simply not qualifying as speech. Aka we can ban spam because we are banning the medium and not the message. This then gets into issues like should flag burning be allowed which blur the line between message and medium. Thus simply saying you support free speech is a rather meaningless statement. People need to look at the specifics on what each group considers speech etc.

If your perjury gets someone else punished when they shouldn't have been, you are an accessory to that unjust punishment. Conversely, if your perjury shields someone from just punishment then you are an accessory to the harm they caused their victim, and potentially future victims who would have otherwise been protected. Once again it is not the speech which is the problem but rather the actual harm which you helped to cause.

That isn't even a question of speech, just private property. If it's your flag then you should be able to burn it, for any reason or no reason. Banning flag-burning on the basis of the message the act is attempting to communicate would obviously infringe on the freedom of speech under even the narrowest of definitions. If you're burning someone else's flag then that can be punished as theft and destruction of others' property independent of any speech which may or may not have been intended. Freedom of speech is not a "get out of jail free" card. If in the course of making your speech you also take actions which harm others then you can be punished for those actions; the fact that they were accompanied by speech is no excuse.

> Thus simply saying you support free speech is a rather meaningless statement.

I kind of agree with you here. Freedom of speech only takes on concrete form when combined with consistent support for private property rights, in which case you get freedom of speech as a natural by-product. The question becomes not "Is this speech?" but rather "Does this action cause injury or otherwise infringe on anyone else's property rights?"—something that speech per se can never do.

Unfortunately that doesn’t work as outlawing harm from speech ends up outlawing political speech because someone doesn’t get elected. Similarly, advertising your product is detrimental to your competition.

Effectively you need to define what kinds of harm speech is allowed to produce. Anti Vaccination videos for example actually get people killed, and we accept that as a valid trade off in the US.

Again, it’s really tempting to define something as outside of free speech but selecting what is and isn’t allowed is kind of the point. So, you can’t simply punt this issue.
