I bought a Roland TD-4S V-Compact do I need speakers? what is the best way to setup the audio portion?

No idea why anyone would hook it to a computer unless they were recording. No computer speakers will properly reproduce electronic drums. Of course you alreaady know you can use headphones, but if you also want a drum amp/monitor, here are a few to choose from. Be aware that the Buttkickers are just sub-woofers, not a complete drum amp.

I don't agree with it and there will always be people who spend their money on those things before the essentials. Though I do think it is an abuse of human rights and privacy to do that. Because they will get those other non-essentials from somewhere. Maybe they will sell the food they buy and sell it at a cheaper price to buy the things they want and have even less food than before. Thus creating a black market in bartering. Vulnerable people with addictions will be exploited on the black market and have even less food. It is cheaper for the government to pay their money into a bank account. And it is up to the individual to spend it anyway they want. If they don't spend it wisely then they can go to their parents, friends, or soup kitchens for food. There are plenty of back up systems there for people who don't spend wisely.
