It's a really bad idea, so much that I registered just to warn you (I live in Venezuela). When there was a severe shortage of cash the government blamed it on banknotes being extracted through the Colombian border for sale at a profit and "hoarding". Arrests were highly publicized, which additionally helped support the conspiracy theory of an "economic war" waged from abroad to destabilize the country.
Now imagine a foreign-looking type caught with a heap of cash: official news outlets are going to have a field day with the arrest photograph:
Los tres hombres se desplazaban en dos vehículos por la carretera nacional San Félix-Upata. Los cuerpos de seguridad, en un trabajo de inteligencia, frustraron el presunto contrabando de extracción de esta cantidad de papel moneda.
The three men were traveling on two vehicles down the San Félix-Upata highway. Security forces, in an intelligence operation, frustrated the presumed extraction contraband of these many banknotes.
In a good scenario, you'll spend a few hours in "the little room" and be relieved of your valuables by the local authorities before they let you go.
I agree that the banknotes are pretty, but please take just a few of each denomination. If anyone asks, it's left over from your daily purchases.
General advice: don't come without a trusted local friend willing to accompany you everywhere, preferably in a car. I'm not exaggerating: Caracas has the 2nd-4th highest murder rate in the world, and $100 can feed a family of four for a month. There are official no-go "peace zones" for law enforcement where kidnappers take their hostages.

BTW, the photo in your question illustrates the amount of cash you needed to buy that toilet paper roll before the Bolívar was redefined so amounts would have 5 less figures (1 new "Bolívares Soberanos" = 100,000 old "Bolívares Fuertes").
