Surely it is true that my own views are also influenced by partisan propaganda. :) However, I think a much stronger influence is that I understand elementary economics, have lived outside Argentina, have operated an Argentine corporation, and have traded forex futures in real markets.
Certainly it is true that the agricultural sector is one of the most powerful in Argentina and that the real estate sector trades in dollars, but most of the rest of your comment is not even wrong, reflecting fundamental misunderstandings of a flat-earth level.
The assertion that the agricultural sector in Argentina is "speculating on the dollar" is incoherent. Speculating on the dollar is an activity dominated by big international investment banks and hedge funds, which make enormous leveraged bets on whether the dollar, the yen, the euro, or other real currencies will go up or down by 0.05%. The agricultural sector in Argentina is not able to do this because of legal prohibitions, and at any rate does not have nearly enough money to engage in the activity profitably.
When people in Argentina talk about the dollar "going higher" what they mean is that the fake Monopoly money we call the Argentine peso is losing value relative to the dollar, whose own changes in value are usually a rounding error by comparison, though not this year. Argentine pesos are an irresponsible speculative investment that are guaranteed to lose value; no prudent investor would hold them.
Anybody who owes debts denominated in Argentine pesos—most notably, the government—has a vested interest in inflation, the devaluation of the peso ("the dollar going higher"). Conversely, anyone who is owed debts denominated in Argentine pesos has a vested interest in the peso appreciating, or, since that's not going to happen, in the peso losing value more slowly. However, overall, the rampant inflation of the peso is one of the factors that makes the Argentine economy unstable and unproductive, which is the bigger factor in play here.
I suspect your reasoning is something along the lines of "the agricultural sector is a big exporter, so they get paid in dollars, so if those dollars are worth AR$600 instead of AR$300 then they make more money." But that is nonsense; if a dollar is "worth" AR$600 instead of AR$300, that's because the peso has lost half its value, so that AR$600 only buys you roughly the same amount of fertilizer, Monsanto seeds, farmhand labor, silage bags, etc., that you could have bought with the AR$300 without the additional inflation. Moreover when inflation is fast enough it becomes difficult to carry out any transactions at all.
It's relevant to point out to other readers that the official dollar, the fake value the exporters of agricultural as well as other goods get paid, is AR$129.25 × AR$137.25 today. That means that for every dollar of soybeans you export legally, you get paid AR$129.25, which is "worth" US$0.41. That is, the central bank confiscates 59% of your revenues (not your profits!) in order to subsidize imports and rich people going abroad for vacations. Unfortunately, soybeans are too bulky to smuggle out of the country.
Government confiscation of 59% of export revenues in order to subsidize Chinese imports goes a long way to explaining how we have ended up in such a terrible economic situation. Argentine makers trying to compete with Chinese imports have the central bank subsidizing 57% of the price of their foreign competition; Argentine consumers only pay 43% (137.25/316). So a hypothetical Argentine product of the same quality must be 57% cheaper than the Chinese product in order to compete. Government mandates of "Industria Argentina" result in companies importing fully manufactured products in kit form from China or Korea and paying unskilled workers a minimal amount to assemble the kits.
Export-led industrialization was the key policy that replaced poverty with prosperity in Taiwan, Japan, PRC, Korea, Indonesia, Singapore, and Malaysia. The Argentine currency policy has been precisely the opposite since *spit* Menem, with brief exceptions under Kirchner and *spit* Macri. Even back to Perón we focused on import substitution rather than exports, although actively sabotaging exporters with monetary policy seems to have started with Menem.
I don't have any idea how big the illegal dollar market is, and neither do you, but it evidently possesses significant liquidity. It has a high impact in people's minds because it's a reliable source of information about what the peso is actually worth; the government has not been a reliable source of that information since Kirchner coerced INDEC into falsifying the inflation numbers, a policy that has continued under Fernández de Kirchner, Macri, and Fernández and which was followed with the "cepo" policy of fake exchange rates that have gutted the Argentine economy over the past 11 years.
Hopefully that answers all of the questions you asked adequately; please feel free to ask for clarification if you feel that any of my answers were incomplete.
