Easy to say, but can you think of any city in North America that‘s addressed those problems that we can look to?
And besides, why do you assume that only poor people do the things I mentioned? Beggars and encampments certainly, but public drug use and defecation, littering and vandalism… that’s all sh#tty people, not poor people business. If having a clean park missing these elements above requires me to pay a few bucks and enjoy a ferry ride, I’m good.
Because you said having a cost keeps those people out. therefore the implication is that people who do those things are poor, and if the island costs money they will not come to it. Yet there are lots of low income people who are not doing the things you are seemingly accusing all low-income people of doing. Why shouldn't they be allowed to enjoy the best part of our city? That's my concern with having a cost to use the island. Maybe we need a program like the low-fare TTC rates to access the island, idk. But I don't think making island access based on your financial situation is either fair or ethical.
To give an example, as a gay dude, if I lose my job, I shouldn't be allowed to access what is essentially the only gay beach in the city because I'm trying to responsibly manage my money until I have a job again? (and yes i realise this forum is usually terrible at understanding why gay people may want to go to gay spaces over straight ones, but I'm not having that fight today) I wouldn't be going there to trash the island, but your position is that in this scenario, I should be financially prohibited from spending a day at the beach with my friends for no fault of my own. And yeah, I know one beach trip isn't gonna usually make-or-break most people's budget, but it's still incredibly unfair.
But yeah, maybe a pedestrian bridge isn't the answer, but we do need a way to make island access equitable.
