Owner cannot get condo association board to make capital improvements

I am a non-driver and have asked the condo association board to install a pedestrian gate where it would be a 10 minute walk to the metro-rail. As it is, we only have a front gate and that makes it a 30 minutes walk in a circle. This has been an unreasonable limit on my entire lifestyle for over 3 years, since I have owned my unit here. It was my mistake not to check if there was a gate, but that simply did not occur to me because it is only logical a gate would be there. It would also be an 8 minute walk to several restaurants and a convenient store, so everyone would benefit, yet the condo association board has done nothing but stonewall. They claim it is a security issue, but that is ridiculous. Locked gates don't give criminals access to our property. It then becomes a cost issue, but a one-time expense for such an accommodation seems more than reasonable, when it is for the common good. It would actually not cost anyone a dime, because our discretionary fund has the money for such purposes as that.

In my opinion, our condo association board is composed of people who are out of touch with reality, and our president is an absentee landlord who cares nothing about people except their rent. This is to me simply unacceptable. That is a larger issue, but in regards to the gate I am truly puzzled, since installation would raise the value of our property and make a difference in the lives of everyone who lives here. I had asked them for some kind of compassion, but it has become clear they have no empathy. I didn't sign up for this and need all of the advice I can get on how to resolve the issue of getting through to them.
