Your right to something shouldn't be based on whether or not you "need" it. I'm fortunate enough to be in a state with open gyms and have nothing but respect for people who are taking risks to work out. Anyways, "needs": gym equipment has proper grips and cushioning for safe use over long periods of time. I'm less likely to blow out my back using proper form at the gym than with Macgyvered equipment at home. I need to go to the gym to use this equipment because lockdowns have caused a shortage and it's really, really, expensive to buy all the equipment yourself. You can also track and improve your performance over time with consistent incremental weights: I know that 10 additional pounds of resistance will always be 10 pounds, something that a bag of rocks can't replicate. Lastly, weight training creates a different physique to body weight training, endurance training/running, etc. You cannot decide that this physique is worth any less than the others.
